To a stirred solution of tert-butyl 4-(1-cyano-2-(thiazol-2-yl)vinyl)piperazine-1-carboxylate (2.25 g), sodium azide (0.4 g) were taken in dry DMSO (4 ml) and heated to 110° C. overnight. The reaction mixture was carefully quenched with water (10 ml) and the reaction mixture was extracted with dichloromethane (3×10 ml). The combined organic layer was washed with brine (10 ml), dried over sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by column chromatography using methanol:chloroform (1:9) as an eluent to afford tert-butyl 4-(5-(thiazol-2-yl)-1H-1,2,3-triazol-4-yl)piperazine-1-carboxylate as white solid.
