A solution of tert-BuOK (2.41 g, 21.52 mmol) in t-BuOH/DME 1:2 (24 ml) was added at 0° C. to a solution of 8-thiabicyclo[3.2.1]octan-3-one (1.53 g, 10.75 mmol) and tosylmethyl isocyanide (2.3 g, 11.83 mmol) in DME (20 ml). The solution was stirred for 3 hours at room temperature. After addition of ether, the mixture was washed with a saturated aqueous NaHCO3 solution, dried over MgSO4 and evaporated. After purification by chromatography on silica gel (hexane/AcOEt 85/15), 8-thiabicyclo[3.2.1]octane-3-carbonitrile was obtained as a colorless oil (1.03 g, 63%).
