Procedure

A solution of 6-(6-bromo-2,3,4-trifluorophenyl)-3,3-dimethylpiperidin-2-one (27.0 mg, 0.080 mmol, described in Intermediate 17) and 10% palladium on carbon in degassed EtOH (2 mL) was stirred under a hydrogen balloon for 3 h. The reaction mixture was filtered through a Celite pad and concentrated in vacuo to provide the title compound. MS: m/z=258 (M+1).
