Procedure

A suspension of 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)acetic acid (100 mg, 0.24 mmol), PyBOP® (125 mg, 0.24 mmol), DIEA (125 μL, 0.24 mmol) in CH2Cl2 (5 mL) stirred at RT for 10-15 minutes. To this solution of activated acid was added 1-methylpiperazine (27 μL, 0.24 mmol) and the reaction mixture was stirred at RT for 1.5 h. Concentrated in vacuo and the crude product was purified using prep HPLC (method 10-35_90 mins) to afford 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)-1-(4-methylpiperazin-1-yl)ethanone. (32 mg, 0.065 mmol, 27%)
