反応手順

To a 25 mL flask with 10 ml of abs. EtOH is added 0.137 g of 4-chloro-6,7-dimethoxyquinazoline and 0.087 g of 1-aminonaphthalene. The solution is heated to reflux whereupon the insoluble materials dissolve. After 5 minutes at reflux a precipatate forms. The solution is allowed to stir an additional 10 min before cooling and isolation of the product as the hydrochloride salt by simple filtration. High-vacuum drying of the solid provided analytically pure (6,7-dimethoxy-quinazolin-4-yl)-alpha-naphthalenylamine (0.142 g, white powder, m.p. 271°-273° C.
