実験手順
2-Amino-N-[3-(2-methylimidazol-1-yl)propyl]benzamide (10.5 g) was dissolved in pyridine (50 ml) and 4-chlorobenzenesulphonyl chloride (12.35 g) was added in portions during five minutes. The temperature of the reaction mixture rose to 45° C. The solution was stirred at room temperature for 4 hours and the pyridine was evaporated in vacuo to give a brown oil. The oil was chromatographed on silica gel, eluting with a mixture of chloroform and methanol (19:1) to give 2-(4-chlorobenzenesulphonamido)-N-[3-(2-methylimidazol-1-yl)propyl]benzamide in the form of a white solid (7 g), m.p. 122°-123° C.
