Procedure: Ethyl 5-nitro-2-(2-(hydroxymethyl)phenylamino)-6-(2-methoxyphenylamino)pyrimidine-4-carboxylate. Ethyl 2-chloro-6-(2-methoxyphenylamino)-5-nitropyrimidine-4-carboxylate (See Example 30.A) (0.300 g, 0.852 mmol), 2-aminobenzyl alcohol (0.125 g, 1.2 mmol) and diisopropylethylamine (0.296 g) were reacted according to General Procedure C, except at room temperature and in dimethylformamide (5 ml). The crude reaction mixture was condensed and purified using Biotage chromatography (60 to 100% EtOAc in hexanes) to afford the title compound (0.323 g, 86%). MS (ESI) m/z 440.5 [M+1]+. The crude reaction mixture condensed purified

Procedure: 2.85 g (14 mmol) of 1-chloro-2,6-dinitrobenzene and 1.73 g (14 mmol) of 2-aminobenzyl alcohol were dissolved in 30 ml of triethylamine and heated under reflux for 24 hours. After concentrating, the residue was purified by silica gel column chromatography. Thus 2.2 g of 2-((2,6-dinitrophenyl)amino) benzyl alcohol was obtained. 0.29 g (1 mmol) of this powder was dissolved in 20 ml of dry dimethylformamide. After adding 40 mg (1 mmol) of sodium hydride (in oil, content: 60%), the reaction mixture was stirred at room temperature for 15 minutes and then at 150° C. for 2 hours. After cooling, 200 ml of ethyl acetate was added thereto and the mixture was washed with water, dried over magnesium sulfate and concentrated. The residue was purified by silica gel column chromatography. Thus 0.14 g of the title compound was obtained. heated under reflux for 24 hours After concentrating the residue was purified by silica gel column chromatography

Procedure: 2-Aminobenzylalcohol (10 g) was dissolved in concentrated hydrochloric acid (25 ml) and the solution diluted with water (20 ml). The solution was stirred at 0° and a solution of sodium nitrite (5.9 g) in water (20 ml) added dropwise. The mixture was stirred at 0° for 40 minutes. The solution was added dropwise to pyridine (92 ml) stirred at 80°. After stirring at 80° for 90 minutes the mixture was concentrated in vacuo and the residue heated with 880 ammonia (100 ml). The mixture was concentrated in vacuo and the residue slurried with water and extracted with ethyl acetate. The ethyl acetate was washed with brine, dried and evaporated. Flash chromatography produced the sub-title compound as a red oil (3.8 g). M.S. m/e 185 Base Peak 80. The mixture was stirred at 0° for 40 minutes stirred at 80° After stirring at 80° for 90 minutes the mixture was concentrated in vacuo the residue heated with 880 ammonia (100 ml) The mixture was concentrated in vacuo extracted with ethyl acetate The ethyl acetate was washed with brine dried evaporated

Procedure: 3-Butyryl-4-chloro-8-methoxyquinoline (2.64 g, 10 mmol) was dissolved in I,4-dioxan (10 ml), 2-aminobenzyl alcohol (1.85 g, I5 mmol) added, and the mixture heated to reflux for 5 minutes. The dioxan was evaporated, water added, and the product extracted into dichloromethane. Chromatography (silica gel, ethyl acetate) and recrystallisation from ethyl acetate gave 3-butyryl-4-(2-(hydroxymethyl)phenylamino)-8-methoxyquinoline (1.86 g, 53%), m.p. 159°-161°. the mixture heated to reflux for 5 minutes The dioxan was evaporated water added the product extracted into dichloromethane Chromatography (silica gel, ethyl acetate) and recrystallisation from ethyl acetate

Procedure: To a mixture of 2-hydroxymethylaniline (25 g), triethylamine (32 ml) and tetrahydrofuran (250 ml) was introduced phosgene generated from trichloromethyl chloroformate (12.2 ml) and active carbon at room temperature with stirring. After stirring for 1 hour at room temperature, the reaction mixture was filtered off and the filtrate was concentrated. The resulting residue was recrystallized from diethyl ether-n-hexane to give 4H-1,2-dihydro-2-oxo-[3,1]benzoxazine (22.3 g). After stirring for 1 hour at room temperature the reaction mixture was filtered off the filtrate was concentrated The resulting residue was recrystallized from diethyl ether-n-hexane
