Procedimiento

A mixture of t-butyl 3-methoxy-4-nitrophenylacetate (0.144 g, 0.539 mmol) and 10% Pd on carbon (0.155 g) in ethyl acetate (8 mL) and methanol (2 mL) was stirred under H2 (40-60 psi) for 2 h. The mixture was filtered through Celite and the filtrate concentrated to afford t-butyl 4-amino-3-methoxyphenylacetate (0.123 g, 96%) as a light yellow oil: 1H NMR (CDCl3, 300 MHz, ppm) 6.70 (m, 3H), 4.04 (bs, 2H), 3.84 (s, 3H), 3.42 (s, 2H), 1.43 (s, 9H).
