Procedure

To a solution of Example 182D (0.643 g, 3.15 mmol) in tetrahydrofuran (31.5 mL) under argon was added dropwise lithium aluminum hydride in tetrahydrofuran (9.45 mL, 18.89 mmol), and the mixture was stirred at room temperature for 30 minutes. Water was added carefully and the mixture was extracted once with dichloromethane. The organic extract was dried over Na2SO4, and the solvent was evaporated to obtain the crude title compound which was used was used without purification for the next reaction. MS (ESI+) m/z 177.3 (M+H)+.
