실험 절차

3-[4-(Methylsulfonyl)phenyl]propan-1-ol (4.02 g, 18.8 mmol) and Dess-Martin periodate (8.49 g, 20.0 mmol) were stirred in DCM (50 ml) at room temperature overnight. The reaction was washed with NaOH solution (1N, 3×25 ml). Sodium triacetoxyborohydide (5.28 g, 25 mmol) was added to the mixture followed by benzyl 4-[(3R)-piperidin-3-ylmethyl]piperazine-1-carboxylate (3.97 g, 12.5 mmol) and magnesium sulphate (20.0 mg). The reaction was stirred at room temperature overnight then washed with water (20 ml) and dried using a phase separation cartridge. Silica was added and the solvent removed under reduced pressure to provide a cake which was added to the top of a silica column. Flash column chromatography (silica, 1%-10% MeOH: DCM) gave the title compound as a yellow oil (5.47 g, 85%).
