Procedure

A solution of 22 mg (0.32 mmol) of 1,2,4-triazole in 5 ml of DMF was cooled to 0° C. and treated with 15 mg (0.29 mmol) of sodium hydride (50% dispersion in refined oil). Subsequently, the mixture was left to warm to room temperature and was stirred for a further 1 hour. 70 mg (0.105 mmol) of tert-butyl (3SR,4RS,5RS)-4-[4-(3 -benzyloxy-propoxy)-phenyl]-3-methanesulphonyloxymethyl-5-(naphthalen-2-ylmethoxy)-piperidine-1-carboxylate were added to this solution. The reaction mixture was heated to 100° C. for 24 hours. For the working-up, the reaction mixture was evaporated under reduced pressure, the residue was partitioned between water and methylene chloride and the organic phase was separated, dried over sodium sulphate and evaporated. For purification, the crude product (70 mg) was chromatographed on silica gel using a 98:2 mixture of methylene-chloride and methanol as the eluent. There were obtained 52 mg (77% of theory) of tert-butyl (3RS,4RS,5SR)-4-[4-(3-benzyloxy-propoxy)-phenyl]-3-(naphthalen-2-ylmethoxy)-5-[1,2,4]triazol-1-ylmethyl-piperidine-1-carboxylate as a colourless solid; MS: 663 (M+H)+.
