Procedure

To a suspension of tert-butyl 5-(2-(3-aminophenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (100 mg, 0.22 mmol) and morpholine-4-carbonyl chloride (51 μL, 0.44 mmol) in CH2Cl2 (2 mL) was added Et3N (61 μL, 0.44 mmol) and catalytic amount of DMAP. The reaction mixture was stirred at RT for 2 h after which 2 equivalents each of morpholine-4-carbonyl chloride and Et3N were added. After 2 h of stirring another 2 equivalents of both the chloride and Et3N were added and continued to stir at ambient temperature for 16 hours. The reaction was concentrated in vacuo and the residue was purified by flash chromatography on silica (12:1 CH2Cl2:MeOH). The product tert-butyl 5-(2-(3-(morpholine-4-carboxamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate was isolated. (80 mg, 65%)
