Reaction Steps

N-(3-ethylphenyl)acetamide (500 mg, 3.06 mmol) and ninhydrin (546 mg, 3.06 mmol) were dissolved in conc. sulfuric acid (10 mL) and stirred at room temperature for 3 hrs. The reaction was stopped by slowing pouring the solution to 150 g of ice and stirring. The reaction mixture was extracted with ethylacetate and water, washed with brine. The washed organic layer was dried over sodium sulfate, concentrated in a vacuum, and purified through silica gel column chromatography (30% ethylacetate in hexane) to afford the title compound (90 mg, 9%).
