실험 절차
17.5 g of sodium hydride (57% in mineral oil) was added, in portions, to a stirred solution of 55.5 g of 1A and 71 g of methyl iodide in 250 ml of tetrahydrofuran at room temperature. The resulting mixture was stirred and refluxed for 2 hours, poured into ice water and filtered. The solid was washed with water, dried and recrystallized from hexane to give N-(3-chloro-4-fluorophenyl)N-methylformamide (5A), as a white crystalline solid, mp: 47°-48° C.
