Procedure

550 mg (1.04 mmol) of 4-nitrophenyl 3-[(phenylcarbonyl)amino]-5-[4-(trifluoromethoxy)phenyl]piperidine-1-carboxylate were initially charged in 14 ml of DMF, and 315 mg (3.12 mmol) of piperidin-4-ol and 144 mg (1.04 mmol) of potassium carbonate were added. The mixture was reacted in a microwave (Emrys Optimizer) at 150° C. for 15 min. The crude product was then purified by preparative HPLC (Reprosil C18, water/acetonitrile gradient). Yield: 430 mg (84% of theory)
