実験手順

2-Fluoro-6-(4-methylbenzyloxy)benzonitrile (241.3 mg; 1 mmol) and guanidine carbonate (180.2 mg; 1 mmol) were heated at 145° C. in dimethyl acetamide for 7 hours. The solvent was removed. Purification by recrystallization in hot ethanol/water yielded 106 milligrams of 5-(4-methylbenzyloxy)quinazoline-2,4-diamine.
