Reaction Conditions

Reaction Steps

A suspension of 2-amino-5-fluorobenzamide (1.00 g, 6.49 mmol), methyl 4-formylbenzoate (1.06 g, 6.49 mmol) and sodium disulfite (1.26 g, 6.62 mmol) in N,N-dimethylacetamide (13 ml) is heated to 150° C. and stirred at this temperature for 3 hours. The reaction mixture is allowed to reach room temperature and poured into ice water. The resulting precipitate is collected by filtration, washed with water and dried under vacuum to afford 4-(6-fluoro-4-oxo-3,4-dihydro-quinazolin-2-yl)-benzoic acid methyl ester as yellow solid; HPLC/MS 2.08 min (C), [M+H] 299.
