Acetic Acid → HCID 57054047, compound

Participants

Reaction Steps

A 250-mL round bottom flask was charged with N-methyl-4-nitroaniline (1.94 g, 12.7 mmol) in tetrahydrofuran (50 mL). To this stirred solution at rt was added acetic acid (14.6 mL, 255 mmol) and sodium cyanate (8.29 g, 127.5 mmol). After 24 h, the reaction mixture was concentrated under reduced pressure. The residue was suspended in water (100 mL) and the resultant solid was isolated by filtration, washing sequentially with dichloromethane and ethyl acetate to afford the title compound (0.63 g, 25%) as a yellow solid. MW=195.18. 1H NMR (DMSO-d6, 500 MHz) δ 8.19-8.14 (m, 2H), 7.58-7.54 (m, 2H), 6.54 (br s, 2H), 3.27 (s, 3H).
