Procedure: 12.6 ml of formic acid were added dropwise at 0° C. to 15 ml of acetic anhydride, and the mixture was then stirred for 2 hours at 60° C. After cooling to 20° C., the mixture was diluted with 140 ml of tetrahydrofuran, cooled to −4° C., and at this temperature a solution of 18.4 g of 2-(2-aminophenyl)ethanol in 185 ml of tetrahydrofuran was added dropwise. After stirring for 3 hours at −6° C. the mixture was neutralised with aqueous potassium hydrogen carbonate solution (25% KHCO3) and extracted four times with 300 ml of ethyl acetate each time. The combined extracts were dried over sodium sulfate and concentrated by evaporation in vacuo. 18.4 g (94% of theory) of the title compound were thereby obtained in the form of yellowish crystals that melted at 49–54° C. After cooling to 20° C. cooled to −4° C. After stirring for 3 hours at −6° C. the mixture extracted four times with 300 ml of ethyl acetate each time The combined extracts were dried over sodium sulfate concentrated by evaporation in vacuo

Procedure: To a solution of 2-aminophenethyl alcohol (4.0 g, 29.16 mmol) in THF (200 mL) was added a solution of 2M phosgene in toluene (17 mL, 34 mmol) at room temperature. The reaction was stirred for 15 minutes, concentrated, and purified with flash chromatography using ethyl acetate (5% 20%) in hexanes to yield 8,9-dihydro-5H-7-oxa-5-aza-benzocyclohepten-6-one (4 g, 84%): 1H NMR (300 MHz, CDCl3) δ 8.02 (bs, 1H), 7.17 (dt, 1H), 7.09 (d, 1H), 6.99 (dt, 1H), 6.90 (d, 1H), 4.51 (t, 2H), 3.21 (t, 2H). concentrated purified with flash chromatography

Procedure: A flask containing 2-aminophenethyl alcohol (565 mg, 4.12 mmol), phthalic anhydride (641 mg, 4.32 mmol) and acetic acid (4 mL) was heated at 100° C. for 1 h. The reaction mixture was poured into water (30 mL) and the solid was filtered off and the solids were washed with water. The crude was purified by flash column chromatography to afford the desired product as white solid (435 mg, 1.63 mmol, 40%). 1H NMR: 1.79 (br s, 1H), 2.78 (t, 2H, J=6.4 Hz), 3.81 (t, 2H, J=6.4 Hz), 7.20 (d, 1H, J=8 Hz), 7.36-7.41 (m, 1H), 7.46 (d, 2H, J=4 Hz), 7.79-7.83 (m, 2H), 7.94-7.97 (m, 21-1). the solid was filtered off the solids were washed with water The crude was purified by flash column chromatography

Procedure: Using an analogous procedure to that described in Example 286, 248.7 mg (1 mmol) of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile in 12 mL of 2-ethoxyethanol and in the presence of 115.6 mg (1 mmol) of pyridine hydrochloride was reacted with 178.3 mg (1.3 mmol) of 2-aminophenethyl alcohol to give 218.4 mg (64.4%) of the product as a pink solid, m.p 159-162° C., mass (electrospray, m/e): M+H 349.9.
