Reaction Steps

A solution of 4-cyano-2-fluorobenzoyl chloride (450 mg) in dichloromethane (5 mL) is added to a solution of amino-hydroxyimino-acetic acid ethyl ester (350 mg) in 2,6-dimethyl-pyridine (1 mL) and the reaction mixture is stirred at room temperature over night. Water is added and the organic phase is separated, washed with 1 N hydrochloric acid, water, and brine, dried over MgSO4, and concentrated in vacuo. The dark residue is heated to 170° C. for 2 h. The crude product is purified by silica gel chromatography (cyclohexane/ethyl acetate 65:35). LC (method 15): tR=1.08 min; Mass spectrum (ESI+): m/z=262 [M+H]+.
