Procedure

One hundred ml of dichloromethane and 20.27 g (0.1 mol) of p-methylthiophenyl chloroformate prepared in the same manner as in Example 1 were placed in a flask, and 50 ml of a dichloromethane solution containing 8.15 g (0.1 mol) of tertamyl alcohol and 8.70 g (0.11 mol) of pyridine was dropped thereto at room temperature. The resulting mixture was then stirred for two hours. The reaction solution was washed with water to remove pyridine hydrochlorate, and the organic layer was concentrated under reduced pressure. Finally excessive pyridine was removed in vacuum whereupon 5.09 g of the desired product, tert-amyl p-methylthiophenyl carbonate was obtained as an oily material (yield 100%).
