Participants

Reaction Steps

To a stirred suspension of 3-methyl-5-(trifluoromethyl)benzyl 4-aminopiperidine-1-carboxylate hydrochloride salt (201 mg, 0.570 mmol) in DCM (5 mL) at RT under nitrogen was added Huenig's Base (0.199 mL, 1.140 mmol). 4-(1H-1,2,3,-triazol-4-yl)butanoyl chloride (99 mg, 0.570 mmol) in DCM (2 mL) was added and the reaction mixture stirred at RT for 2 hours. The reaction mixture was diluted with DCM and washed with a 10% solution of citric acid, and saturated brine solution, before the organic portion was dried over MgSO4, filtered and concentrated under reduced pressure. Purification was carried out by chromatography on silica using 0-10% MeOH in DCM as eluent to afford the title product;
