Procedure

3-(5-Bromo-3-methylpyrid-2-ylamino)propylamine (1.0 g) was reacted with 3,4-dimethoxy-1,2,5-thiadiazole-1-oxide (0.65 g) in methanol overnight. p-Fluorobenzylamine (0.51 g) was added and the reaction mixture was stirred for 2 hours. The product was filtered off and recrystallised from ethanol to yield 4-(p-fluorobenzylamino)-3-[3-(5-bromo-3-methylpyrid-2-ylamino)propylamino]-1,2,5-thiadiazole-1-oxide (0.77 g, 40%) m.p. 125°-126° C.
