Reaction Steps

100 mg (2.76 mmol) of 2-hydroxy-4-[3-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)-1-propynyl]benzoic acid and 5 ml of methanol are introduced into a round-bottomed flask and 29 mg (2.76 mmol) of diethanolamine are added. The reaction medium is stirred for one hour and evaporated to dryness, and the residue obtained is triturated from a mixture of heptane and ethyl ether (50/50). The solid is filtered off and dried. 100 mg (78%) of diethanolamine salt are collected, with a melting point of 100-5° C.
