실험 절차

A solution of 100 g (0.789 mol) of 1-ethyl-4-oxopiperidine in 1000 mL of acetone was stirred at rt in a water bath. To this was added 62.2 mL (142 g, 1 mol) of methyl iodide, dropwise at such a rate to keep the temperature below 30 degrees. A precipitate developed within minutes and the mixture was stirred at rt for 4 h. The mixture was filtered and the precipitate washed with acetone and dried to afford the title compound as a white solid. Mass spectrum (ESI) 142 (M+).
