Procedure
A solution of 7-(2-methoxyethoxy)-3,4-dihydroquinazolin-4-one (500 mg, 2.2 mmol) in thionyl chloride (15 ml) and DMF (0.1 ml) was heated at reflux for 3 hours. The volatiles were removed by evaporation to give 4-chloro-7-(2-methoxyethoxy)quinazoline hydrochloride as a cream solid (520 mg, 83%).
