Procedure: 4,6-Dichloropyrimidine-5-carbonyl chloride (590 mg, 2.79 mmol, prepared according to E. V. Tarasov et al. Synlett 2000, 5, 625-626) was dissolved in dichloromethane (3 ml) and TEA (389 μl, 2.79 mmol) was added. To this solution, 3-fluoro-5-methoxyaniline (394 mg, 2.79 mmol) dissolved in 3 ml dichloromethane was added dropwise and the mixture was stirred for 30 min. The reaction mixture was then diluted with dichloromethane, washed with 4% sodium bicarbonate solution, dried over magnesium sulphate, filtered and evaporated. The crude (800 mg, 56% purity, 51% yield) was used in the next synthetic step without further purification. was added dropwise washed with 4% sodium bicarbonate solution dried over magnesium sulphate filtered evaporated The crude (800 mg, 56% purity, 51% yield) was used in the next synthetic step without further purification

Procedure: 3-fluoro-5-methoxyaniline (115 mg, 0.82 mmol) was reacted with 8-(1-bromoethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide hydrobromide (100 mg, 0.20 mmol) using an analogous procedure to the one described in Example 3.03 to give 8-(1-(3-fluoro-5-methoxyphenylamino)ethyl)-N,N-dimethyl-2-morpholino-4-oxo-4H-chromene-6-carboxamide (60 mg, 63%) as a white solid. Mass Spectrum: M+H+ 470.

Procedure: 2-Chloro-6-methyl-4-pyridinecarbonyl chloride (44.087 g, 0.232 mol) in acetone (1 l) was treated with ammonium isothiocyanate (21.192 g, 0.278 mol) and the mixture was stirred for 1 hour at room temperature. Subsequently, a solution of 3-fluoro-5-methoxybenzenamine (36.02 g, 0.255 mol) in acetone (200 ml) was added dropwise and the reaction mixture was stirred for 4 hours at room temperature. The solvent was evaporated in vacuo and the residue was dissolved in CH2Cl2 (1 l). This organic solution was washed (H2O), dried (MgSO4), filtered and the solvent was evaporated in vacuo to yield a brown solid. The brown solid was triturated in acetonitrile (0.8 l), stirred overnight and the solid was filtered off and dried (vacuum oven, 4 hours at 65° C.). Yield: 59.69 g of intermediate D13 (73%). the reaction mixture was stirred for 4 hours at room temperature The solvent was evaporated in vacuo the residue was dissolved in CH2Cl2 (1 l) This organic solution was washed (H2O) dried (MgSO4) filtered the solvent was evaporated in vacuo to yield a brown solid The brown solid was triturated in acetonitrile (0.8 l) stirred overnight the solid was filtered off dried (vacuum oven, 4 hours at 65° C.)
