Reaction Steps

A cooled mixture of ethylchloroformate (0.45 g) in pyridine was treated with a solution of N5 -[2-[[[5-[(dimethylamino)methyl]-2-thienyl]methyl]thio]ethyl]-1-methyl-1H-1,2,4-triazole-3,5-diamine (0.7 g) in pyridine (8 ml). Sodium carbonate (2 g) and water (10 ml) were added and the mixture evaporated in vacuo. The residue was dissolved in water (15 ml) and extracted with hot isopropanol (30 ml). The extract was evaporated and the residue purified by column chromatography (silica:methanol:0.88 ammonia; 79:1) to give the title compound (0.48 g).
