Acetic Acid → HCID 178513835, compound

Participants

Reaction Steps

Into 15 ml of acetic acid saturated with nitrogen, 2.84 g (0.01 mol) of oxamide 3-(phenoxymethyl)phenylhydrazone was dissolved, and 1.36 g (0.011 mol) of 2-fluorobenzaldehyde was added to the thus formed solution under nitrogen atmosphere and the mixture was stirred for 16 hours at room temperature. After adding water saturated with nitrogen to the mixture, the precipitated crystals were collected by filtration and dried under vacuum. The thus dried crystals were recrystallized from a mixed solvent, saturated with nitrogen, of ethyl acetate and n-hexane to obtain 3.38 g of 5-(2-fluorophenyl)-4,5-dihydro-1-[3-(phenoxymethyl)phenyl]-1H-1,2,4-triazole-3-carboxamide melting at 176°-178° C. in a yield of 86.7%.
