Conditions

Temperature: 50 °C

Procedure

To a solution of [(3aR,4R,6R,6aR)-6-(6-amino-9H-purin-9-yl)-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl]methyl acetate (0.200 g, 0.572 mmol) in AcCN (3 mL) was added phenylisocyanate (0.068 g, 0.572 mmol) dropwise. The white mixture was stirred for two hours at ambient temperature, overnight at 50° C. and then concentrated to give the title compound (0.268 g, 100%).
