Sodium Hydroxide → HCID 19004322, compound

Participants

Reaction Steps

A solution of 4-[[[2-(2-naphthalenyloxy)ethyl]amino]carbonyl]-alpha-oxobenzeneacetic acid methyl ester (0.35 g) in methanol (5 mL) and tetrahydrofuran (5 mL) was treated with 1N sodium hydroxide (1 mL) and after 5 minutes the mixture was 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 acetone-hexane provided 0.275 g of purified 4-[[[2-(2-naphthalenyloxy)ethyl]amino]carbonyl]-alpha-oxobenzeneacetic acid as a colorless solid, mp 173°-175° C.
