Procedure

A solution of 3.0 g of 5-benzoylaminomethyl-2-thiophenesulfonyl chloride, in 100 ml of dichloromethane, is added to a stirred mixture of 3.0 g of 4-[4-(1H-imidazol-1-yl)phenoxy]butaneamine dihydrochloride (Example 2) and 3.5 ml of 10N NaOH in 100 ml of water. The mixture is stirred at room temperature for 3 hours, a tacky precipitate being formed. The precipitate is mixed with 100 ml of concentrate HCl, and the mixture is stirred at reflux for 12 hours, solution taking place. The solution is taken to dryness in vacuo, and the dihydrochloride salt of the title compound was recrystallized from aqueous ethanol, m.p. 230°-232° C. (dec.); yield, 0.5 g.
