Reaction Steps

A solution of 2-chloro-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-quinoline-3-carbonitrile (0.25 g, 1.06 mmol), cyclopentylamine (0.136 g, 1.6 mmol) and triethylamine (0.154 ml, 0.11 g, 1.1 mmol) in ethyl alcohol (3 ml) was heated at reflux for 3 h. Then water (10 ml) was added and the mixture was extracted by dichloromethane. The extract was concentrated under reduced pressure and the residue was purified by column chromatography on silica gel (CH2Cl2-hexane, 1:1) to give the title compound (0.145 g, 48%).
