Reaction Steps

In the same manner as in the above example, the intermediate formed from 1 g of 5,8,11-eicosatriynoic acid and 0.7 g of CDI is treated with 0.727 g of para-hydroxyaniline. The medium is then stirred for 24 hours at room temperature. Water is then added gradually to the mixture until all the product formed precipitates. It is drained and dried and then recrystallized in isopropyl ether. 0.85 g of N-(para-hydroxyphenyl)-5,8,11-eicosatriynamide is obtained in the form of beige-white crystals of melting point 121° C.
