Participants

Reaction Steps

To a solution of the product of Example 2 (670 mg, 2.18 mmol) dissolved in anhydrous THF (22 mL) was added a solution of LAH (1.0 M solution in THF, 2.18 mL, 2.18 mmol) dropwise. After completion of addition the reaction mixture was stirred at room temperature for 3 hours. The reaction mixture was diluted with water. The aqueous layer was extracted with ethyl acetate (3×). All combined organic layers were dried over Na2SO4, filtered, and concentrated to provide an oil (587 mg, 1.98 mmol), which was used in the next step without any further purification (91% yield). 1H (CDCl3 7.34 (4H, s), 4.68 (2H, s), 4.57 (2H, s), 3.80, 600 MHz): δ (2H, t, J=5.2 Hz), 3.56 (2H, t, J=5.3 Hz), 1.69 (1H, br s), 0.90 (9H, s), 0.07 (6H, s); 13C (CDCl3 140.4, 138.3, 128.0, 127.2, 73.2, 71.9, 65.4, 150 MHz): δ 63.0, 26.2, 18.6, −5.0.
