Participants

Reaction Steps

To a solution of 2-aminobenzaldehyde (1 g, 8.26 mmol) and Et3N (1.15 ml, 8.26 mmol) in DCM (50 ml) was added propionyl chloride (0.72 ml, 8.26 mmol) and the resulting mixture stirred at RT for 3 days. The mixture washed with water, sat. NaCl, dried over MgSO4, filtered and evaporated to afford the title compound 1.4 g (96%). 1H NMR (CDCl3): 1.30 (t, J 7.6 Hz, 3H), 2.51 (q, J 7.6 Hz, 2H), 7.23 (m, 1H), 7.62 (m, 1H), 7.69 (m, 1H), 8.78 (m, 1H), 9.94 (s, 1H), 11.19 (brs, 1H).
