실험 절차

3-Iodo-imidazo[1,2-a]pyridine-7-carboxylic acid hydrazide (0.18 g, 0.59 mmol) was treated with triethylorthoacetate (3 ml) and concentrated H2SO4 (1 drop). The mixture was heated at 80° C. o/n, allowed to cool, solid was filtered off and washed with EtOH and dried to afford 0.165 g of product. MS: [M+H]+ 327
