Procedure

To sodium hydride (60% wt. suspension in mineral oil, 108 mg) in dry DMF (5 ml) was added methyl thioglycolate (160 ul) dropwise at 0° C. After 30 minutes added 4-methanesulfonyl-piperidine-carboxylic acid tert-butyl ester (500 mg) as a solution in DMF (1.5 ml) and the reaction mixture was warmed up to room temperature over 5 hours. Aqueous work-up and purification on silica yielded 4-methoxycarbonylmethylsulfanyl-piperidine-1-carboxylic acid tert-butyl ester (414 mg).
