Reaction Steps

In a round bottom flask 6-Iodo-7-methoxy-3H-quinazolin-4-one (500 mg, 1.65 mmol), triphenyl phosphine polymer (2.75 gm, 3 mmol/gm) and carbon tetrachloride (2.53 gm, 16.5 mmol) were combined in 3 mL of dichloroethane and heated at reflux for 5 hours. 5-Aminoindole (686 mg, 1.65 mmol) was added to the mixture and heated at 50° C. overnight. Reaction mixture was concentrated in vacuo and the residue was chromatographed on silica gel 20% MeOH/1% ammonium hydroxide (NH4OH)/CHCl3 to provide 186 mg (28%) of product as a pale yellow solid.
