Reaction Steps

To a flask containing 1-acetyl-5-amino-3-phenyl-1H-indazole (300 mg, 1.2 mmol) was added dichloromethane (10 mL), 4-(dimethylamino)pyridine (75 mg, 0.6 mmol) and triethylamine (180 mg, 1.8 mmol). The mixture was allowed to stir for ten minutes. Terephthalic acid monomethyl ester hydrochloride (285 mg, 1.44 mmol) was then added and stirring continued for 18 hours. The mixture was quenched with 5% sodium bicarbonate and extracted with dichloromethane. The extracts were dried using sodium sulfate, filtered and condensed to give a solid. The solid was recrystallized in ethanol to give the title compound (368 mg, 75%/; yield). ES-MS (m/z) 414 [M+1]+.
