실험 절차
Of the compound from Example 22A, 75 mg (0.25 mmol) were introduced in 1.5 ml of THF and admixed at 0° C. in small portions with 43.25 mg (0.26 mmol) of 4-nitrophenyl formate. The mixture was stirred at 0° C. for 2 h and then at RT overnight. The solvent was removed on a rotary evaporator and the residue was taken up in DMSO and purified by preparative HPLC (method 10). This gave 66 mg (81% of theory) of the title compound.
