Procedure
To a solution of the product from step 1 (520 mg, 0.73 mmol) in tetrahydrofuran (10 mL) at 5° C. was added ammonium hydroxyde (30%, 2 mL) and the reaction was stirred at 5° C. for 40 minutes. The mixture was diluted with ethyl ether, washed with saturated sodium bicarbonate, dried (magnesium sulfate), and evaporated to provide the title compound (490 mg) containing p-nitrophenol (˜10%). 1H NMR (DMSO-d6): δ 0.93 (3H, s), 0.96 (3H, s), 1.2 (9H, s), 1.6 (2H, t), 2.45 (1H, dd), 2.78 (1H, d), 2.85-2.95 (2H, m), 3.3-3.6 (3H, m), 3.7 (1H, quartet), 3.8 (3H, s), 3.96 (2H, t), 5.0 (1H, d), 6.4 (2H, br s), 6.6 (1H, d), 7.05 (2H, d), 7.10-7.25 (5H, m), 7.7 (2H, d).
