Reaction Steps

To a solution of 2,5-dichloroquinazolin-8-ol (1 eq) (See example 32 for synthesis) in DMF was added iodomethane (3 eq) and potassium carbonate (3 eq). The reaction mixture was stirred at room temperature for overnight. Diluted with ethyl acetate and washed with water and brine and dried over sodium sulfate. Filtered, evaporated and dried to provide product as a yellow solid in quantitative yield. ES/MS m/z 229.0 (MH+). Proceed for next step.
