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, 0.72 mmol) in CH2Cl2:DMF (4 mL:0.5 mL) stirred at RT for 10-15 minutes. To this solution of activated acid was added 2-methoxyethanamine (21 μL, 0.24 mmol) and the reaction mixture was stirred at RT for 3 h. Concentrated in vacuo and the crude product was purified using prep HPLC (method 10-35—90 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-(2-methoxyethyl)acetamide. (25 mg, 0.053 mmol, 22%)
