Procedure
A solution of 2.7 g of 4-[4-(1H-tetrazol-1-yl)phenoxy]butaneamine hydrochloride (Example 39) in 100 ml of water is treated successively with 3.5 ml of 10N NaOH and a solution of 2.7 g of 4-bromobenzenesulfonyl chloride in 100 ml of diethyl ether. The mixture is stirred at room temperature for 1.5 hours, the precipitate collected, washed with diethyl ether and water, and air dried. Recrystallization from ethanol gives the pure compound, m.p. 109°-110° C.; yield, 1.6 g.
