Reaktionsschritte
A suspension of 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)acetic acid (120 mg, 0.29 mmol), PyBOP® (150 mg, 0.29 mmol), DIEA (152 μL, 0.87 mmol) in CH2Cl2 (5 mL) was stirred at RT for 10-15 minutes. To this solution of activated acid was added N-methylpropan-2-amine (30 μL, 0.29 mmol). The reaction mixture was stirred at RT for 3 h and concentrated in vacuo. The crude product was purified using prep HPLC (method 5-25-50_80 mins) and was further washed with ethyl ether and drops of CH2Cl2 to afford 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)-N-isopropyl-N-methylacetamide. (12 mg, 0.025 mmol, 9%)
