Participants

Reaction Steps

240 mg (60% in oil; 6 mmol) of sodium hydride are added to a solution of 1.43 g (12 mmol) of 3-hydroxybenzonitrile in 10 ml of dimethylformamide and the mixture is stirred at room temperature for 1 hour under nitrogen. 200 mg (1.2 mmol) of 4-(2-chloroethyl)-1H-imidazole hydrochloride and tetrabutylammonium iodide (catalytic amount) are added and the mixture is heated for 3 hours at 80° C. The solvent is evaporated under reduced pressure and the oily residue is stirred in ethanol and filtered. The filtrate is evaporated and the residue is purified by chromatography on a column of silica gel (first eluent chloroform, second eluent 95/5 chloroform/methanol). The title compound is converted to the oxalate and crystallized from a 2/1 ethanol/diethyl ether mixture, M.p.: 189°-190° C.
