Ethyl Acetate → 7-(4-Nitrobenzylsulfamoyl)imidazo[5,1-b]thiazole

Participants

Reaction Steps

4-Nitrobenzylamine (1.24 g) and 2 ml of diisopropylethylamine were added to a solution of 0.95 g of 7-chlorosulfonylimidazo[5,1-b]thiazole in 20 ml of DMF. The mixture was stirred at room temperature for 12 hr. Ethyl acetate was added to the reaction mixture. The mixture was washed with water and saturated brine in that order. The organic layer was dried over anhydrous magnesium sulfate. The solvent was evaporated, and the resultant powder was collected by filtration to give 1.07 g of 7-(4-nitrobenzylsulfamoyl)imidazo[5,1-b]thiazole.
