Versuchsvorschrift
2,4-dichloro-7-methoxyquinazoline (500 mg, 2.183 mmol) was suspended in 2% aqueous NaOH (6 mL). THF (1 mL) was added and the reaction was stirred for 4 h. The reaction was diluted with water and the solid that remained was filtered off. The aqueous phase was diluted with 1 N HCl. The precipitate that formed was filtered, washed with water and dried to give 2-chloro-7-methoxyquinazolin-4-ol (288 mg, 63% yield). MS: MS m/z 211.1 (M++1).
