실험 절차

3-Methylsulfonylaniline (1.4 mmol, 0.3 g), 3-oxo-2-(2-oxo-2-phenyl-ethyl)-butyric acid ethyl ester (1.4 mmol, 0.35 g), triethylamine (1.4 mmol, 0.14 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 were separated and the solvents removed under vacuum. The crude material was purified over silica gel to yield the named product as an oil. The structure of the compound was verified by 1H-NMR (CDCl3, ppm): 1.36 t (3H), 2.45 s (3H), 2.82 s (3H), 4.3 q (2H), and 6.8-7.2 m (9H).
