Participants

Reaction Steps

To a mixture of 2-mercapto-1-methylimidazole (1.14 g, 10 mmoles), 0.6 of 60% sodium hydride in mineral oil and 20 ml of N,N-dimethylformamide was added 1.88 g (10 mmoles) of 4-chloro-3-nitroanisole. The mixture was stirred at room temperature for 0.5 hours and then heated at 90°-100° C. for 4 hours. After cooling in an icebath, 0.5 ml of acetic acid was added and the mixture was partitioned between dichloromethane and dilute sodium bicarbonate. The organics were concentrated on a steam bath to a small volume and the residue was chromatographed on silica gel using ethyl acetate as the eluent. The fractions containing the product were combined and concentrated to give 1.0 g (38%) of the product, mp 117°-120° C.).
