Acetonitrile → HCID 11775698, compound

Participants

Reaction Conditions

Reaction Steps

Seven grams (34.5 mmol) of 2,2,2-trifluoro-N-(4-methylphenyl)acetamide, 18.49 g (68.9 mmol) of diphenyl chlorophosphate, 6.97 g (68.9 mmol) of triethylamine, and 35 ml of acetonitrile were introduced into a 100 ml flask and reacted for 18 hours while being refluxed (82° C.). After the reaction, the reaction solution was cooled to room temperature, 25 ml of ethyl acetate was added thereto, and the precipitate was then filtered off. The filtrate was subjected to solvent removal by evaporation, and the crude product thus obtained was purified by column chromatography (silica gel, ethyl acetate:hexane=3:7), resulting in 6.77 g of N-(4-methylphenyl)-2,2,2-trifluoroacetimidoyl chloride as a yellow liquid (yield: 88.6%).
