Reaction Conditions

Reaction Steps

To a cooled solution of 66.46F (452.7 mg, 1.3 mmol) in dry THF (10 mL) at 0° C. was added LAH (1.0 M in THF) (2.7 mL, 2.7 mmol) dropwise. Upon complete addition, the reaction was maintained at 0° C. and was monitored by TLC and LCMS. After 45 minutes, 1N NaOH was added to quench the reaction. The resulting solution was extracted three times with EtOAc. After drying over anhydrous magnesium sulfate, filtration, and concentration, the residue was purified by flash chromatography (silica gel 60, eluted with 0%-50% EtOAc in hexanes). Fractions containing the desired product were combined and concentrated to provide 66.46G as a colorless oil (330.4 mg, 80%). 1H NMR (400 MHz, CDCl3) δ ppm 7.33 (3H, m), 7.03 (1H, m), 6.84 (2H, m), 5.51 (1H, s), 4.69 (2H, s), 4.08 (2H, q, J=2.5 Hz), 3.77 (3H, s), 3.67 (2H, t, J=5.3 Hz), 3.00 (1H, s), 2.13 (2H, m).
