Ethyl trifluoroacetate → HCID 885871, compound

Participants

Reaction Steps

To 3,5-dimethoxyaniline (20 g, 131 mmol) dissolved in anhydrous tetrahydrofuran (90 mL) was added 4-(dimethylamin) pyridine (1.6 g, 13.1 mmol) and ethyl trifluoroacetate (47 mL, 392 mmol). After refluxing 48 hours, the cooled reaction mixture was concentrated and partitioned between ethyl acetate (300 mL) and 2N hydrochloric acid (100 mL). The ethyl acetate layer is washed with water (100 mL), dried using anhydrous sodium sulfate, and concentrated to yield N-(3,5-dimethoxyphenyl)-2,2,2-trifluoroacetamide (31.8 g, 98%) as a pale yellow solid.
