To a solution of tert-butyl(5-methoxy-2-nitrobenzyloxy)dimethylsilane (14.0 g, 47.1 mmol) in EtOH (200 mL) was added 10% Pd/C (1.40 g), the mixture was stirred at 30° C. for 2 hours under H2 (40 psi). The solids were filtered off and the filtrate was concentrated under reduced pressure to give the product (14.0 g) as a yellow oil. 1H NMR (DMSO 400 MHz): δ 6.75 (d, J=2.4 Hz, 1H), 6.60-6.55 (m, 2H), 4.55 (s, 2H), 4.40 (brs, 2H), 3.61 (s, 3H), 0.90 (s, 9H), 0.09 (s, 6H).
