Reaction Steps
To a stirred solution of ethyl 3-amino-2-methylbenzoate (1.00 g, 5.58 mmol) in DCE (20 ml) was added benzaldehyde (569 μl, 5.58 mmol) followed by acetic acid (0.64 ml, 11.2 mmol). The reaction was stirred at room temperature for 1 h and then sodium triacetoxyborohydride (1.77 g, 8.37 mmol) was added and the reaction stirred for 2 h. Distilled water (20 ml) was added and solid NaHCO3 was added until the aqueous phase was pH7 and the phases were separated. The aqueous phase was washed with DCM (2×5 0 ml), the combined organics were then washed with brine (50 ml), dried using Na2SO4, filtered and evaporated to afford the title compound as a yellow oil (1.52 g, 96%) which was used in the next stage without any further purification. LC-MS 95%, m/z=270.0, 1H NMR (500 MHz, Chloroform-d) δ 7.42-7.32 (m, 4H), 7.32-7.28 (m, 1H), 7.17-7.06 (m, 2H), 6.73 (dd, J=7.8, 1.1 Hz, 1H), 4.40 (s, 2H), 4.36 (q, J=14.3, 5.3 Hz, 2H), 4.08 (br. s, 1H), 2.35, (s, 3H), 1.39 (t, 3H).
