To a solution of 4-(toluene-4-sulfonyloxymethyl)-piperidine-1-carboxylic acid tert-butyl ester (9.765 g, 26.43 mmol) in methanol (1 00mL) at room temperature was added sodium thiomethoxide (5.557 g, 79.29 mmol, Aldrich). The reaction mixture was stirred at room temperature for 2 h then concentrated. The residue was taken in methylene chloride and washed with water (3×) and brine (1×). The organic layer was dried over anhydrous sodium sulfate and concentrated to give a clear oil as crude product of 4-methylsulfanylmethyl-piperidine-1-carboxylic acid tert-butyl ester (6.37 g).
