Reaction Steps

A mixture of 5-chloro-2-hydroxybenzoic acid methyl ester (0.50 g, 2.7 mmol), hydrazine monohydrate (0.3 mL, 6.2 mmol) and ethanol (5 mL) was refluxed for 6 hours. After the reaction mixture was cooled to room temperature, n-hexane was added and the separated crystal was filtered to give the title compound (395.9 mg, 79.2%) as a white crystal.
