By replacing in Example 296 (3-n-butylamino-4-phenoxy-5-sulfamylbenzyl)benzylamine with an equimolar amount of (4-benzyl-3-n-butoxy-5-sulfamylbenzyl)benzylamine (prepared as described in Example 184) and following the hydrogenation procedure described, crude 4-benzyl-3-n-butoxy-5-sulfamylbenzylamine is obtained. The crude amine is dissolved in ethanol (50 ml) and a saturated solution of dry hydrogen chloride in ethanol (2 ml) is added to precipitate, after cooling, 4-benzyl-3-n-butoxy-5-sulfamylbenzylamine hydrochloride. After filtration and recrystallization from ethanol it is obtained as a hydrate with a melting point of 176°-179° C.
