실험 절차

To a suspension of 3-chloro-5-cyanobenzyl 4-aminopiperidine-1-carboxylate hydrochloride salt (195 mg, 0.591 mmol) in DCM (5 mL) at RT under nitrogen was added Huenig's Base (0.206 mL, 1.182 mmol). 5-(1H-1,2,3-Triazol-4-yl)pentanoyl chloride (111 mg, 0.591 mmol) in DCM (2 mL) was then added and the reaction mixture stirred for 20 hours. The reaction mixture was diluted with DCM and washed with a 10% solution of citric acid, a saturated solution of brine and the organic portion was then dried over MgSO4, filtered and concentrated under reduced pressure. Purification was carried out by chromatography on silica using 0-10% MeOH in DCM to afford the title product.
