Reaction Steps

2-Fluoro-5-trifluoromethyl-benzaldehyde (1 g) is dissolved in toluene (5 ml) and thereto are added ethyl 7-ethylamino-heptanoate (3.98 g) and potassium carbonate (2.88 g) and the mixture is heated under reflux overnight. The reaction solution is cooled to room temperature, and thereto are added water and ethyl acetate, and the mixture is separated, and the organic layer is washed with a saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue is purified by silica gel column chromatography (hexane:ethyl acetate=97:3→83:17) to give ethyl 7-[ethyl-(2-formyl-4-trifluoromethyl-phenyl)-amino]-heptanoate (1.29 g). MS (m/z): 374 [M+H]+
