The alcohol 29 (135 mg, 0.56 mmol) is dissolved in ethyl acetate (0.82 ml). Pyridine (0.081 ml) is then added, followed by 4-nitrophenyl chloroformate (275 mg, 2.4 eq.). After one night at room temperature, the solvent is evaporated off. Chromatography on silica gel gives the carbonate 30 (206 mg, 91%).
