실험 절차

54 mg (0.49 mmol) of 3-hydroxyazetidine hydrochloride, 97 mg (0.46 mmol) of sodium triacetoxyborohydride and 0.13 ml (2.35 mmol) of acetic acid were added in succession to a solution of 90 mg (0.32 mmol) of the compound of Example 36A in 3.2 ml of dichloromethane, and the mixture was stirred at RT for 1 h. A little water was then added, and the mixture was concentrated on a rotary evaporator. The residue was purified by preparative HPLC (Method 18). Evaporation of the appropriate fractions and drying of the residue under high vacuum gave 60 mg (66% of theory) of the title compound as the product of the reaction.
