Reaction Steps
A solution of 4,5-Dichloro-8-quinazolinol (0.6 g, 2.8 mmol) in dichloromethane is added to a saturated solution of dimethylamine gas in dichloromethane. The reaction mixture is stirred for 30 minutes, re-saturated with dimethylamine gas, stirred for 30 minutes and concentrated in vacuo to obtain a yellow solid. The solid is added to a 2.5% hydrochloric acid/ethyl acetate mixture. The mixture is filtered and the filter cake is washed with water and dried in a vacuum oven to give the title product as a white solid, 0.35 g, mp 232° C. (dec.).
