with formamide in water
Steps:
3 EXAMPLE 3
A mixture of 2-amino-5-fluorobenzoic acid (2.07 g) and formamide (4 ml) was heated at 160° C. for 2 hours, and for a further 2 hours at 180° C. The reaction mixture was allowed to cool and water was added. The reaction product was filtered off and washed with water and with diethyl ether to give 6-fluoro-3,4-dihydroquinazolin-4-one in 78% yield: m.p. 269-271° C.; Elemental Analysis: Found C, 58.2; H, 3.0; N, 16.9; C8 H4 N2 OF requires C, 58.9; H, 2.5; N, 17.2%.
