Reaction Conditions

Reaction Steps

Stir and cool to 0° C. a mixture of N-(5-chloro-2-cyanophenyl)acetamide (see Example 8, 1.0 g, 5.14 mmol) and THF (10 mL) and add potassium tert-butoxide (6.2 mL, of a 1M solution in THF) and stir at 0° C. for 30 min. Add bromoethyl acetate (0.6 mL) in one portion. Stir at room temperature for 2 h. Quench the reaction with water (40 mL) and stir with ethyl acetate. Separate the layers and reextract the aqueous with ethyl acetate. Combine the organic extracts and wash with water and brine. Dry over MgSO4 and concentrate under reduced pressure to obtain a brown solid. Triturate the solid with ether and collect a beige solid. Chromatograph the solid on silica gel with 2% ethyl acetate/dichloromethane followed by 10% ethyl acetate/dichloromethane to obtain 0.65 g (45%) of the title compound as a beige solid: MS 281(M+H), HPLC: Rt=3.20 min., TLC (silica gel, 10% ethyl acetate/dichloromethane) Rf=0.53.
