Reaction Steps
The compound was prepared according to general procedure E with 5-iodovanillin (1.8 mmol) in dry acetone (25 ml), anhydrous K2CO3 (2.4 mmol), and ethylbromoacetate (2.7 mmol) at reflux for 1 h15. Ethanol was added and evaporated by azeotropic distillation with ethylbromoacetate. 673 mg of crude product were obtained and purified by silica gel chromatography (eluent dichloromethane). 320 mg of purified compound were obtained (49% yield). 1H NMR (250 MHz, CD3COCD3): δ 1.28 (t, J=7.2 Hz, 3H), 3.97 (s, 3H), 4.23 (q, J=7.2 Hz, 2H), 4.85 (s, 2H), 7.55 (s, 1H), 7.95 (s, 1H), 9.90 (s, 1H) 13C NMR (126 MHz, CD3COCD3): δ 15.2, 57.4, 62.1, 70.5, 92.4, 113.9, 135.1, 135.5, 153.1, 169.4, 191.1. MS (ESI): m/z 364.9 [M+H]+.
