50% | With sulfuric acid In ethanol; toluene | A. Ethyl 2-amino-5-fluorobenzoate 2-Amino-5-fluorobenzoic acid (1.0 g, 6.4 mmol) was dissolved in ethanol (15 mL) and toluene (10 mL). Several drops of concentrated H2SO4 were added. The reaction was refluxed with a Dean Stark trap overnight. The reaction was cooled to rt and the solvents removed in vacuo. The product was isolated by chromatography on silica gel (4*15 cm column) eluted with chloroform/ methanol (98:2, v/v-500 mL followed by 95:5, 500 mL) in 50percent yield.
