Reaction Steps

A suspension of tert-butyl 5-(6-acetoxy-2-(3-aminophenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (0.50 g, 0.98 mmol), nicotinoyl chloride hydrochloride (0.224 g, 1.26 mmol) and DIEA (0.45 g, 3.48 mmol) in CH2Cl2 (15 mL) was stirred at RT for 7 h. The volatiles were removed in vacuo and the residue was purified by preparative TLC (SiO2, CH2Cl2:MeOH 9:1) to give the product tert-butyl 5-(6-acetoxy-2-(3-(nicotinamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (0.374 g, 0.608 mmol, 62%).
