Procedure

A 2.66 g quantity of 4-methylbenzoyl chloride was added dropwise to 50 ml of a solution of 1.00 g of 5-chloro-4-hydroxy-2-pyridone in pyridine. The mixture was subjected to reaction at room temperature overnight. The pyridine was distilled off and the residue was stirred in ether for 6 hours. The solids thus precipitated were dried, giving 1.71 g of the title compound. The ether was concentrated and the residue was applied to silica gel column chromatography using as an eluent petroleum ether-chloroform (1:2), affording 0.85 g of the same compound (total amount 2.56 g, total yield 97%).
