Procedure

A suspension of 2-(dimethylamino)acetic acid (57 mg, 0.55 mmol), PyBOP® (286 mg, 0.55 mmol), DIEA (240 μL, 1.38 mmol) in CH2Cl2 (2 mL) was stirred at RT for 10-15 minutes. This solution of activated acid was added to a suspension of tert-butyl 5-(2-(3-aminophenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (500 mg, 1.10 mmol) and CH2Cl2 (4 mL). The reaction mixture was stirred at RT for 1.5 h. Activated another 1.5 equivalent of the acid as described above and stirred for 16 h. Diluted with more CH2Cl2 and extracted with H2O (3×). Organic layer was dried under Na2SO4 and concentrated in vacuo. The residue was purified by flash chromatography on silica (9:1 CH2Cl2:MeOH) to give the desired product tert-butyl 5-(2-(3-(2-(dimethylamino)acetamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate. (570 mg, 1.06 mmol, 96%).
