Procedure

To a solution of toluene-4-sulfonic acid 4,4-difluorocyclohexylmethyl ester (100 mg, 0.33 mmol)) in N,N-Dimethylformamide (0.5 mL) was added sodium azide (32 mg, 0.49 mmol). The reaction mixture was stirred at 90° C. for 90 min, cooled to room temperature and diluted with dichloromethane (5 mL). The organic layer was washed with water (2×5 mL), collected, dried over anhydrous sodium sulfate, filtered, and concentrated to provide the title compound which was used without further purification.
