Reaction Steps

Sodium hydride (502 mg, 60% in mineral oil) was added portionwise to 4-chloro-2-fluorobenzonitrile (2.04 g) and 3,5-dihydroxybenzaldehyde (1.81 g) in DMF and the solution heated to 80° C. for 16 h. The cooled solution was diluted with water, acidified with concentrated hydrochloric acid, extracted twice with ethyl acetate, the extracts dried over sodium sulphate and evaporated. Purification by chromatography gave the sub-title compound as a white solid (0.83 g).
