실험 절차
A solution of 740 mg (1.84 mmol) of the compound from Example 104A in 20 ml of tetrahydrofuran was added dropwise to 5.5 ml (5.5 mmol) of a 1N solution of diisobutylaluminum hydride in dichloromethane in 20 ml of tetrahydrofuran at RT under argon. The mixture was stirred at RT for 2 h and then water and dichloromethane were added, and the phases were separated. The aqueous phase was extracted with dichloromethane. The combined organic phases were washed with saturated aqueous sodium chloride solution, dried over sodium sulfate, filtered and concentrated. The residue was purified by preparative HPLC (mobile phase: acetonitrile/water gradient). 437 mg (66% of theory) of the title compound were obtained.
