YieldReaction ConditionsOperation in experiment
With hydrogenchloride; In ethyl acetate; N,N-dimethyl-formamide; Intermediate 2: Ethyl (4-chloro-2-cyanophenoxy)acetate A solution of <strong>[13589-72-5]4-chloro-2-cyanophenol</strong> (5.0g) in N,N-dimethylformamide (20mL) was added dropwise to an ice-cooled suspension of sodium hydride (60% oil dispersion, 1.4g) in N,N-dimethylformamide (165mL). The resultant mixture was stirred at 0-5C for 40 minutes, then ethyl bromoacetate (3.9mL) was added and stirring was continued for 1.5 hours. Ethyl acetate and hydrochloric acid (1M) were added and the layers were separated. The organic layer was washed with water, aqueous sodium bicarbonate solution and brine, then dried over sodium sulphate and filtered. The filtrate was evaporated to give crude ethyl (4-chloro-2-cyanophenoxy)acetate (7.8g) as a yellow oil which was used without further purification.
With potassium carbonate; In acetone; for 10h;Heating / reflux; To a solution of <strong>[13589-72-5]5-chloro-2-hydroxy-benzonitrile</strong> (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, 1 H), 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).
Intermediate E: Ethyl (4-chloro-2-cyanophenoxy)acetate [Show Image] A solution of <strong>[13589-72-5]4-chloro-2-cyanophenol</strong> (5,0g) in N,N-dimethylformamide (20mL) is added dropwise to an ice-cooled suspension of sodium hydride (60% oil dispersion, 1.4g) in N,N-dimethylformamide (165mL). The resultant mixture is stirred at 0-5C for 40 minutes, then ethyl bromoacetate (3.9mL) is added and stirring is continued for 1.5 hours. Ethyl acetate and hydrochloric acid (1M) are added and the layers were separated. The organic layer is washed with water, aqueous sodium bicarbonate solution and brine, then dried over sodium sulphate and filtered. The filtrate is evaporated to give crude ethyl (4-chloro-2-cyanophenoxy)acetate (7.8g) as a yellow oil which is used without further purification.
