Sodium Hydroxide → 2-[2-[3-[2-[4-(Cyclobutyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid sodium salt

Participants

Reaction Steps

A solution of 0.418 g of (E)-2-[2-[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid in 10 ml of ethyl alcohol was mixed at room temperature with 5.0 ml of 0.2N sodium hydroxide solution. This mixture was warmed on a steam bath until all the solids had solubilized. After cooling the reaction mixture was condensed in vacuo at 40° C. to constant weight to yield E)-2-[2-[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid sodium salt as a white solid.
