Reaction Steps
To a solution of 4-(7-aminoquinazolin-2-ylamino]-benzenesulfonamide (1 eq) (For synthesis see example 43) in THF was added acetic acid (5 eq), HBTU (4 eq) and DIEA (10 eq). The reaction mixture was stirred at room temperature for 48 h. The reaction does not go to completion. Diluted with ethyl acetate and washed with water, brine and dried over sodium sulfate. Filtered, concentrated and purified by semi-prep HPLC to provide N-(2-(4-sulfamoylphenylamino) quinazolin-7-yl)acetamide ES/MS m/z 358.0 (MH+).
