Reaction Steps

To a solution of di-tert-butyl dicarbonate (114.6 mg) in chloroform (2 ml) was added 4-dimethylaminopyridine (6 mg). A solution of 4-amino-2-chlorobenzotrifluoride (98.1 mg) in chloroform (2 ml) was added and the reaction mixture stirred for 20 minutes at room temperature. A solution of 1-[(1-methylpiperidin-3-yl)methyl]piperazine (98.5 mg) in chloroform (2 ml) was added and the resulting solution was stirred at reflux for 18 hours. The reaction mixture was purified by column chromatography on silica gel (20 g) using a gradient of 100% dichloromethane through to 20% methanolic ammonia in dichloromethane to give the title compound (14 mg).
