Reaction Steps
To a mixture of 4-(methyloxy)-2-(trifluoromethyl)benzaldehyde (14 g, 65 mmol, 1.0 equiv), aqueous NH3 (25-28%, 370 mL, 5.20 mol, 80 equiv), and MeOH (300 mL) was added Raney-Ni (3.8 g, 65 mmol, 1.0 equiv). The flask was fitted with a hydrogen balloon, and the mixture was stirred for 7 days at room temperature. The reaction mixture was filtered through a celite cake, and the filtrate was concentrated. The residue was purified by HPLC to afford 9 g (64%) of the title compound as the trifluoroacetate salt. MS (ES+): m/e 206 [M+H]+. 1H NMR (400 MHz, DMSO-D6) 7.6 (d, 1H), 7.3 (d, 1H), 7.2 (s, 1H), 4.1 (s, 2H), 3.8 (s, 3H)
