Reaction Steps

A mixture of 2-chloro-6-nitro-quinoline (1.6 g, 7.67 mmol) in N-methyl-2-pyrrolidinone (15 ml) with the above described rac-6-fluoro-2,3-dihydro-benzofuran-3-ylamine (1.3 g, 8.43 mmol) and N-ethyldiisopropylamine (1.96 ml, 11.5 mmol) was stirred at 140° C. for 2 h. Cooled to room temperature, poured onto water and extracted twice with Ethyl acetate, dried over sodium sulfate and evaporated totally to give a crude product which was purified by silica gel column chromatography with heptane/dichloromethane followed by trituration with diethyl ether to give the title compound as a yellow solid (1.0 g, 40%); MS (ISP) m/e=326.2 (M+H+).
