Procedure

A solution of 200 mg of the compound from Example 36A with a purity of 90% (0.35 mmol) in 4 ml of tetrahydrofuran was added dropwise to 1.2 ml (1.2 mmol) of a 1N solution of lithium aluminum hydride in tetrahydrofuran in 2 ml of tetrahydrofuran at RT under argon. The mixture was stirred at RT for 15 min and then 1N hydrochloric acid was 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 66 mg (51% of theory) of the title compound as mixture of diastereomers.
