Methyl 4-Formylbenzoate → HCID 90411589, compound

Participants

Reaction Steps

To a magnetically stirred solution of methyl 4-formylbenzoate (1.71 g, 10.41 mmoL) dissolved in EtOH (mL) was added (4-(trifluoromethoxy)phenyl)-hydrazine hydrochloride (2 g, 10.41 mmoL) and the reaction was stirred at room temperature overnight. The solvent was concentrated under reduced pressure and dried under high vacuum to give (E)-methyl 4-((2-(4-(trifluoromethoxy)phenyl)-hydrazono)methyl)benzoate (3.08 g, 87%): mp 142-145° C.; 1H NMR (400 MHz, CDCl3) δ 10.10 (s, 1H), 8.04 (d, J=8.0 Hz, 2H), 7.72-7.65 (m, 3H), 7.13 (q, J=8.9 Hz, 4H), 3.93 (s, 3H); 19F NMR (376 MHz, CDCl3) δ −58.36; ESIMS m/z 338 ([M+H])+.
