Reaction Steps

27.6 g of pentachlorobenzonitrile and 32 g of 3,5-di-tert-butyl-4-hydroxyphenylpropionic acid 2-aminoethylamide are reacted with 11 g of triethylamine in 200 g of N-methylpyrrolidone for 7 hours at 100° C., after which 500 g of water and 400 g of toluene are added, and the toluene phase is separated off while still hot and evaporated down under reduced pressure. The residue is boiled with 0.15 l of ethanol, and the mixture is left to stand overnight at room temperature. The precipitate is then filtered off under suction and dried. After recrystallization from toluene, the product melts at 173°-175° C.
