3-Bromo-4-fluorobenzaldehyde → N-[(E)-(3-bromo-4-fluorophenyl)methylideneamino]-2-(4-chloroanilino)acetamide

Participants

Reaction Steps

2-(4-Chlorophenylamino)acetohydrazide (B) (101 mg, 0.51 mmol) and 3-bromo-4-fluorobenzaldehyde (104 mg, 0.51 mmol) were refluxed in ethanol (3 mL) for 15 hours. After cooling to room temperature the precipitate was collected by filtration, washed with ethanol (20 mL) and water (20 mL). Drying in vacuo yielded the title compound (129 mg, 66%) as a colorless powder. 1H NMR δ (ppm) (DMSO-d6): 3.84 and 4.28 (2 H, two d), 6.01 and 6.25 (1 H, two br s), 6.62-6.69 (2 H, m), 7.12-7.17 (2H, m), 7.47-7.51 (1 H, m), 7.77-7.83 (1 H, m), 8.01 and 8.25 (1 H, two s), 8.05-8.12 (1H, m), 11.63 (1 H, two s). LCMS (10 cm_apci_formic) Rt 3.85 min; m/z 384/386/388 [M+H].
