Reaction Steps

To a mixture of methyl 2-amino-4-methoxybenzoate (5.4 g, 30.0 mmol) and chloroacetonitrile (2.8 mL, 45.0 mmol) was added anhydrous hydrogen chloride (4M solution in 1,4-dioxane, 20.0 mL, 80 mmol) and the reaction mixture was stirred at 50° C. for 30 minutes. After cooling it to room temperature the resulting slurry was diluted with diethyl ether (100 mL) and the stirring was continued for an additional 30 minutes. The off-white precipitate was collected by filtration, washed with diethyl ether and dried in vacuo to provide 2-(chloromethyl)-7-(methyloxy)quinazolin-4-ol hydrochloride (7.5 g, 96%). MS (EI) for C10H9ClN2O2: 225 (MH+).
