실험 절차

A solution of 36.3 mg (0.061 mmol, purity 70%) of the compound from Example 61A in dichloromethane (2.0 ml) was admixed with 0.03 ml (21.6 mg, 0.21 mmol) of triethylamine and then 12.3 mg (0.061 mmol) of 4-nitrophenyl chloroformate were added at RT. The mixture was stirred at RT for 2 h and then the reaction solution was washed with saturated aqueous sodium hydrogencarbonate solution and water, and the organic phase was dried over magnesium sulphate, filtered and concentrated under reduced pressure. Yield: 56.2 mg (91% of theory, purity 60%)
