Reaction Conditions:

with acetic acid in ethanol at 110; for 24 h;Inert atmosphere;Sealed tube;

Steps:

3.2.2. Method 2

General procedure: The 2-aminobenzamide (1 equiv), the orthoester (2-3 equiv) and absolute ethanol (2-3 mL) wereplaced in a 15-mL Chemglass screw-cap pressure tube (No. CG-1880-01, Chemglass, Vineland, NJ,USA). Glacial acetic acid (3 equiv) was added, N2 was introduced to the vessel and the cap wastightened. The vessel was heated at 110 °C for 12-72 h, then cooled and concentrated to give thequinazolinone, which was purified by crystallization from absolute ethanol or trituration from 5%ether in pentane. The following compounds were prepared:
