Procedure

To a solution of 4-hydrazino-2-methylquinazoline dihydrochloride (100 mg, 0.40 mmol) and triethylamine (0.14 mL, 0.81 mmol) in ethanol (3 mL) was added 61 mg (0.4 mmol) of 4-methoxyacetophenone. The resultant solution was refluxed overnight and the resultant reaction mixture was absorbed directly on Si gel. Purification by automated Si gel chromatography (gradient 100% hexanes to 100% ethyl acetate) on the Flashmaster II was performed yielding 50 mg (36%) of the titled compound as a bright yellow solid. HPLC Purity: 91%.
