PROCEDURE
实验过程
A mixture of 1-[4-(4-chlorophenyl)-2-methanesulfonyloxy-n-butyl]imidazole hydrochloride (2.0 g), 4-acetylaminothiophenol (1.2 g) and anhydrous potassium carbonate (2.0 g) in 30 ml of acetone and 10 ml of methanol was stirred and refluxed overnight under nitrogen. The solvent was evaporated and the residue treated with water (50 ml) and ether (20 ml) and the mixture stirred until crystallization was complete. Filtration of the product and recrystallization from ethyl acetate gave 1.84 g of 1-[4-(4-chlorophenyl)-2-(4-acetylaminophenylthio)-n-butyl]imidazole as a pale cream solid, m.p. 165.5°-166.5° C. B. Similarly, proceeding as above substituting the appropriate thiophenol for 4-acetylaminothiophenol the following compounds are prepared:
