15 g (0.05 mol) of 1-benzyl-3-(5-carboxy-2-furyl)indazole and 36.43 g (0.31 mol) of thionyl chloride in 400 ml of benzene were heated under reflux for 3 h. The cooled mixture was filtered and concentrated. This gave 11.95 g (approximately 76%) of the title compound which was used for subsequent reactions without any further purification.
