실험 절차

A mixture of 1.25 g of 1H-imidazol-1-propanamine in 25 ml of water was stirred at room temperature then 2.34 g of N-acetylsulfanilyl chloride was added and stirring was continued for 20 hours resulting in a clear solution. With the addition of 4 ml of 5N sodium hydroxide the solution turned milky and resulted in the separation of an oil. The addition of dichloromethane resulted in the formation of a suspended precipitate which was collected by filtration and gave 2.67 g of the desired compound as tan crystals, mp 178°-180° C.
