A solution of 2-(1-Boc-piperidin-4-ylmethylamino)-5-chloro-N-(2-pyridyl)benzamide (6.1 g, 14 mmol) in trifluoroacetic acid (125 mL) was stirred at 70° C. for 2 h, then at room temperature for 24 h. The solution was concentrated in vacuo, and the residue was directly applied to a silica gel column. Elution with dichloromethane—2 M ammonia in methanol (9:1) afforded 4.2 g (89%) of the pure title compound, as a yellow solid.
