The reaction mixture was stirred at RT for 2.5 h. The reaction mixture was concentrated in vacuo to remove volatiles. The residue was poured into ice-water and the resulting white solid was filtered and dried for several hours under high vacuum. The crude product re-crystallized using absolute EtOH to afford tert-butyl 5-(2-(3-(2-morpholinoacetamido)-phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate. (830 mg, 75%)
