Reaction Steps

To a stirred solution of 2,6-dichloro-4-phenyl-quinoline-3-carboxylic acid ethyl ester (prepared as described in example 11 step B, 200 mg, 0.58 mmol) in DMSO (2 ml) in sealed tube, was added pyrrolidine (0.073 ml, 0.89 mmol), K2CO3 (153 mg, 1.11 mmol) and the mixture was stirred at 90° C. for 3 h. After cooling, the crude mixture was diluted with water and extracted with ethyl acetate. The organic phases were combined and washed with brine, dried over sodium sulfate and concentrated in vacuo to give a crude residue which was purified by flash column chromatography (100-200 mesh silica, eluting with 10% ethyl acetate in hexane) to obtain 6-chloro-4-phenyl-2-pyrrolidin-1-yl-quinoline-3-carboxylic acid ethyl ester (150 mg, 68%) as pale yellow solid. LC-MS: 381 (M+H)+.
