Sodium Hydroxide → HCID 19004485, compound

Participants

Reaction Steps

A mixture of 4-[[2-(2-naphthalenyloxy)acetyl]amino]-alpha-oxobenzeneacetic acid methyl ester (0.7 g) in hot methanol (10 mL) and sufficient tetrahydrofuran to dissolve the solids was treated with 1N sodium hydroxide (2.5 mL) and diluted with water. The organic solvent was removed under vacuum and the residue was mixed with water, acidified with excess 2N hydrochloric acid, and extracted with dichloromethane. The organic layer was dried (Na2SO4), faltered, and evaporated to give the crude product. Crystallization from acetone-hexane provided 0.61 g of 4-[[2-(2-naphthalenyloxy)acetyl]amino]-alpha-oxobenzeneacetic acid as a colorless solid, mp 215°-216° C.
