1,1-Dimethylhydrazine → HCID 86748126, compound

Participants

Reaction Steps

A mixture of 4-[2-(2-naphthalenyloxy)ethoxy]-alpha-oxobenzeneacetic acid methyl ester (3.5 g), 1,1-dimethylhydrazine (2.28 mL) in methanol (40 mL), tetrahydrofuran (20 mL) and one drop of glacial acetic acid was refluxed for 48 hours and evaporated to dryness. The crude mixture was separated by HPLC (dichloromethane-ether, 49:1) and the more polar component was crystallized from dichloromethane-methanol to provide 0.9 g of (E)-alpha-(dimethylhydrazono)-4-[2-(2-naphthalenyloxy)ethoxy]benzeneacetic acid methyl ester as a colorless solid, mp 137°-138° C.
