Tris(hydroxymethyl)aminomethane → (E)-2-[2-[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid tris-(hydroxymethyl)-amino-methane salt

Participants

Reaction Steps

A mixture of 0.418 g of (E)-2-[2-[3-[2-[4-(cyclobutyl)-2-thiazolyl]ethenyl]phenylamino]-2-oxoethyl]benzoic acid and 0.1214 g of tris-(hydroxymethyl)-amino-methane were solubilized in 10 ml of ethyl alcohol with warming 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 tris-(hydroxymethyl)-amino-methane salt as a white solid.
