To 5.2 (1.1530 g, 3.079 mmol) in THF (10 mL) at 0° C. was added LAH (1.0 M solution in THF (4.619 mL, 4.619 mmol)). The reaction was stirred for one hour and then carefully diluted with water, extracted with EtOAc, washed with brine, dried over sodium sulfate, filtered, and concentrated to provide 5.3 (0.9050 g, 96.57% yield).
