Procedure

Combine 3.46 g (0.019 mole) 1-bromoheptane and 5.16 g (0.018 mole) N-(2,6-dimethylphenyl)-2-[1H-imidazol-1-yl]ethane sulfonamide in 10 ml DMF and heat to 100° C. Follow progress of reaction by TLC on silica gel (acetonitrile:ammonium hydroxide, 9:1). After about 10 hours, allow reaction mixture to cool to room temperature. Pour the reaction mixture into 50 ml H2O and extract with 1×25 ml ether to give a white precipitate in the aqueous layer. Filter and recrystallize the precipitate from acetone to provide the title compound
