実験手順

To a stirred mixture of 5-methyluridine (12.8 g, 50 mmol) in pyridine (75 mL) at 0° C. was added methanesulfonyl chloride (17.4 mL, 225 mmol). The reaction mixture was stirred at 0° C. for five hours then poured into ice-water (500 mL) with stirring. Trimethanesulfonyl-5-methyluridine (2) precipitated and the mixture was stirred for 5 min. The solid product was collected by filtration and washed with water (3×200 mL) and dried. Yield, 21.6 g, 89%.
