Carbon Tetrachloride → (6,7-Diethoxy-quinazolin-4-yl)-(3-ethynyl-phenyl)-amine Hydrochloride

Participants

Reaction Steps

6,7-Diethoxyquinazolin-4-one (120 mg, 0.512 mmol), triphenylphosphine (295 mg, 1.126 mmol) and 3 mL of carbon tetrachloride were refluxed for 16 hours. The reaction mixture was concentrated in vacuo to a residue which was diluted with 3 mL of isopropyl alcohol and 3-ethynylaniline (66 mg, 0.563 mmol) and refluxed for 3 hours. The cooled reaction mixture was filtered to afford solid title product which was washed with 10 mL of isopropyl alcohol and dried in vacuo at 70° C., 140 mg (75%); mp 269°-270° C.
