A mixture of 3-amino-4-benzyl-5-sulfamylbenzyl bromide hydrobromide (1.1 g; prepared as described in Example 61), n-butylamine (5.0 ml) and methanol (10 ml) is stirred at 22°-25° C. for 24 hours. The resulting solution is then diluted with water (20 ml) to precipitate crude (3-amino-4-benzyl-5-sulfamylbenzyl)-n-butylamine. After filtration and recrystallization from aqueous ethanol it is obtained with a melting point of 141°-143° C.
