4-(Pyridin-3-yloxy)benzohydrazide → HCID 178506232, compound

Participants

Reaction Steps

4-(pyridine-3-yloxy)benzohydrazide (2.33 g, 10.2 mmol) was dissolved in ca. 70 mL of anhydrous pyridine and S-methyl N-[4-chloro-3-(trifluoromethyl)phenyl]isothiourea hydroiodide (4.04 g, 10.2 mmol) was added. The reaction mixture was refluxed for 18 hrs under Ar. The pyridine was removed in vacuo and the resulting residue was purified by silica gel chromatography using EtOAc as eluent to give the title product (0.56 g) as a white solid.
