실험 절차

A solution of 6.68 g (17.2 mmol) of the compound from Example 29A in 100 ml of tetrahydrofuran was added dropwise to 60 ml (60 mmol) of a 1N solution of lithium aluminum hydride in tetrahydrofuran under argon in 300 ml of tetrahydrofuran at RT. The mixture was stirred at RT for 15 min and then, while cooling in ice, 1N hydrochloric acid was added. The mixture was extracted with ethyl acetate, and the organic phase was dried over magnesium sulfate, filtered and concentrated. The residue was purified by flash chromatography on silica gel (mobile phase: toluene/ethyl acetate gradient). 5.93 g (99% of theory) of the target compound were obtained.
