Reaction Steps

To 10% Pd/C (5 g, 4.7 mmol, prewetted with DMF) was added a solution of methyl 2-[N-(tert-butoxycarbonyl)-N-(4-trifluoromethylbenzyl)aminomethyl]-4-methoxycinnamate (34.52 g, 72 mmol) in methanol (100 mL). The mixture was shaken under hydrogen (50 psi) in a Parr apparatus for 7 hr, then was filtered through a pad of celite® to remove the catalyst. The filtrate was concentrated to afford the title compound (34.15 g, 98%) as a colorless oil: 1H NMR (400 MHz, CDCl3) δ 7.58 (d, J=8.1 Hz, 2H), 7.31 (br s, 2H), 7.09 (d, J=8.4 Hz, 1H), 6.76 (dd, 1H), 6.66 (s, 1H), 4.47 (br s, 2H), 4.40 (br s, 2H), 3.76 (s, 3H), 3.63 (s, 3H), 2.79 (br s, 2H), 2.47 (t, 2H), 1.48 (s, 9H.
