Versuchsvorschrift
2-chloro-7-methoxyquinazolin-4-ol (288 mg, 1.368 mmol) was dissolved in Dimethylamine 2 M in THF (2 ml, 4.00 mmol) and heated to 100° C. for 1 h in a sealed tube. The reaction was cooled and the volatiles were removed under vacuum. The crude solid was collected and washed with water, filtered and dried to give 2-(dimethylamino)-7-methoxyquinazolin-4-ol which was carried to the next step without further purification. MS: MS m/z 220.1 (M++1).
