Procedure

To a stirred solution of 1-benzyl-4-(1,1,1-trifluoro-2-(trimethylsilyloxy)propan-2-yl)piperidine (3 g, 8.3 mmol) in THF (30 mL), tetrabutylammonium fluoride (3.2 g, 12.4 mmol) was added slowly at RT. The reaction mixture was stirred for 3 h. After completion of the reaction, the mixture was quenched with saturated ammonium chloride solution, extracted with ethyl acetate. The organic layer was washed with brine solution and dried over anhydrous sodium sulfate and concentrated under vacuum to afford 2-(1-benzylpiperidin-4-yl)-1,1,1-trifluoropropan-2-ol product. [M+1]=288.15
