Reaction Steps

A mixture of (E)-alpha-(dimethylhydrazono)-4-[2-(2-naphthalenyloxy)ethoxy]benzeneacetic acid methyl ester (0.45 g) in warm methanol (3 mL) and tetrahydrofuran (10 mL) was treated with 1N sodium hydroxide (2 mL), heated on the steam bath for one hour, and the mixture was diluted with water and concentrated to remove the organic solvents. The residue was acidified with excess hydrochloric acid and extracted with dichloromethane containing a little tetrahydrofuran. The organic layer was washed with water, dried (Na2SO4), filtered and evaporated to give crude product. Crystallization from dichloromethane-hexane provided 0.38 g of pure (E)-alpha-(dimethylhydrazono)-4-[2-(2-naphthalenyloxy)ethoxy]benzeneacetic acid as a colorless solid, mp 135° C. with decomposition.
