実験手順
To a mixture of 5.0 g of 2-(2,2-diphenyl ethyl)-2-imidazoline and 50 ml of pyridine, 1.1 g of acetyl chloride was dropwise added and the solution stirred at room temperature for about 2 hours. After the reaction, pyridine was removed by distillation. To the resulting residue there was added 100 ml of benzene and the same amount of water, and the solution was well shaken. The benzene layer was separated, washed with water and dried with sodium sulfate. After removing benzene from the solution, the resulting residue was recrystallized from ether to give 1-acetyl-2-(2,2-diphenyl ethyl)-2-imidazoline having a melting point of 104°-106° C.
