Reaction Steps
To a solution of ethyl 2-(4-chloro-2-formyl-anilino)-2-oxo-acetate (0.14 g, 0.55 mmol, 1 eq) in 5.5 mL of acetic acid was added ammonium acetate (0.42 g, 5.4 mmol, 10 eq). After heating at 115° C. for 1 h, the mixture was concentrated then diluted with H2O and extracted with ethyl acetate. The organic layer was concentrated and the residue was purified on silica gel column chromatography (hex:EtoAc 3:2) to give ethyl 6-chloroquinazoline-2-carboxylate (0.11 g, 0.48 mmol, 88%).
