2-(2-Ethoxyethoxy)-6-hydrazinyl-4-(trifluoromethyl)pyridine → HCID 70018612, compound

Participants

Reaction Steps

1.40 g of N-(1-(methylthio)-2-nitroethenyl)methanesulfonamide (Intermediate No. 57), 1.80 g of 6-(2-ethoxyethoxy)-4-trifluoromethyl-2-pyridylhydrazine and 11 ml of ethanol were stirred for 15 hours under heating and refluxing and then cooled to room temperature, whereupon precipitated crystals were collected by filtration. The crystals obtained by filtration were washed with a small amount of ethanol and then dried to obtain 0.97 g of N-(1-(6-(2-ethoxyethoxy)-4-trifluoromethyl-2-pyridyl)hydrazino-2-nitroethenyl)methanesulfonamide (Compound No. 164) having a melting point of 153° C.
