Reaction Steps

m-Fluoroaniline (5 mmol, 0.6 g), 2-benzoyl-4-oxo-pentanoic acid ethyl ester (5 mmol, 1.2 g), and tosic acid (0.1 g) were combined in ethanol, then heated under reflux. The resulting oil was resuspended in chloroform, then washed with water, 5% sodium bicarbonate, and brine. The organic layer was dried over NaSO4, then the solids filtered away and the solvents removed under vacuum. The named product was recrystallized from ethanol (m.p. 100° C.-101° C.).
