실험 절차

Combine 1.89 gm. (0.01 M) N-(2,6-dimethylphenyl)crotonamide, 0.90 gm. (0.0107 M) lysidine, 0.01 gm. (~0.001 M) methanesulphonic acid and about 40 ml. of ethanol in a pressure bottle and heat (bath temp. 100°-110° C.) for about 100 hours. Remove the solvent in vacuo, add about 50 ml. of water. Adjust the pH to 8.0 with concentrated HCl, and extract the aqueous phase with 2×25 ml. methylene chloride. Then adjust the aqueous phase to pH 13 with 50% sodium hydroxide and extract with 3×30 ml. of methylene chloride. Wash the combined methylene chloride extracts with 2×5 ml. of water. Dry the methylene chloride extracts over sodium sulfate. Evaporate off the solvents to obtain the title compound.
