실험 절차

4-(5-Bromo-3-methylpyrid-2-ylamino)butylamine (0.7 g) in methanol was reacted with 3,4-dimethoxy-1,2,5-thiadiazole-1-oxide (0.44 g) overnight at room temperature. Methanolic ammonia (25 ml) was added and the reaction mixture was stirred for 2 hours. After evaporation, the residue was recrystallised from a mixture of acetonitrile and ether to yield 4-amino-3-[4-(5-bromo-3-methylpyrid-2-ylamino)-butylamino]-1,2,5-thiadiazole-1-oxide (0.45 g, 45%) m.p. 212°-214° C. dec.
