Participants

Reaction Steps

N-{3-Bromo-4-[5-(4-methylbenzoyl)-1-methyl-1H-pyrrol-2-ylmethyl]phenyl}methane-sulfonamide (320 mg, 0.69 mmol) was dissolved in DMF. CuCN (120 mg, 1.38 mmol) was added and the suspension was refluxed for 4 h. The mixture was cooled to room temperature, and NaCN (2.0 g in 10 ml of water) was added. After 0.5 h the mixture was extracted with ethyl acetate and the extracts were washed with water, and brine, and dried over sodium sulfate. The solvent was removed in vacuo and the residue was purified by preparatory TLC (hexane-ethyl acetate) to give N-{3-cyano-4-[5-(4-methylbenzoyl)-1-methyl-1H-pyrrol-2-yl-methyl]phenyl}methanesulfonamide (190 mg, 67%) as a solid, mp 171-172° C.
