Reaction Steps

A mixture of 2-hydroxy-5-methoxybenzaldehyde (46 mg, 0.3 mmol), tert-butyl 4-(chloromethyl)-1H-indazole-1-carboxylate (80 mg, 0.3 mmol), and K2CO3 (166 mg, 1.2 mmol) in DMF (1.0 mL) was heated at 80° C. for 2 h. The mixture was filtered and the solid was washed with DCM. The filtrate was concentrated and purified on silica gel using a mixture of EtOAc and hexanes as eluent to give tert-butyl 4-((2-formyl-4-methoxyphenoxy)methyl)-1H-indazole-1-carboxylate (88 mg, 77%) as a colorless oil.
