A solution of 1.30 g (2.85 mmol) of the compound from Example 99A in 20 ml of THF was added dropwise to 10 ml (9.98 mmol) of a 1N lithium aluminum hydride solution in THF under argon in 80 ml of THF at RT. 1N hydrochloric acid was then added, the mixture was extracted with dichloromethane, and the organic phase was dried over magnesium sulfate, filtered and concentrated. The crude product was purified by preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 0.73 g (61% of theory) of the title compound.
