Procedure

To a suspension of tert-butyl 5-(2-(3-aminophenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (20 mg, 0.044 mmol) and 1-(2,2,2-trifluoroacetyl)pyrrolidine-2-carbonyl chloride (880 μL, 0.088 mmol, 0.1M solution in CH2Cl2) was added Et3N (12 μL, 0.088 mmol), catalytic amount of DMAP, and CH2Cl2 (1 mL). The reaction mixture was stirred at RT for 2 h after which 2 equivalents each of 1-(2,2,2-trifluoroacetyl)pyrrolidine-2-carbonyl chloride and Et3N were added. 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 (10:1 CH2Cl2:MeOH). The product tert-butyl 5-(2-(3-((R)-1-(2,2,2-trifluoroacetyl)pyrrolidine-2-carboxamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate was isolated. (130 mg, 46%)
