Reaction Steps
To a solution of 5-chloro-2-hydroxy-benzonitrile (10 g, 65.0 mmol) in acetone (100 mL) was added ethylbromoacetate (11 g, 71.4 mmol) followed by K2CO3 (19.7 g, 143 mmol). After heating at reflux for 10 h, the mixture was filtered and the filtrate was concentrated to afford the desired product (15.3 g), which was used in the next step without further purification. 1H NMR (CDCl3): 7.57 (d, J=2.5 Hz, 1H), 7.48 (dd, J=9.0, 2.5 Hz, 1H), 6.81 (d, J=9.0 Hz 1H), 4.78 (s, 2H), 4.28 (q, J=7.1 Hz, 2H), 1.32 (t, J=7.1 Hz, 3H).
