Reaction Steps

In a 250 ml flask fitted with a mechanical stirrer and a reflux condenser, were placed 30.7 g (0.12 mole) of the 2-hydroxy-3,4,6-trimethylbenzoic acid phenyl ester prepared in step (2) and 42.36 g (0.12 mole) of didodecylamine. This mixture was heated in a nitrogen atmosphere at 120° C. for 12 hours. The phenol formed was distilled off under vacuum (7 g were thus collected). After cooling, the crystallization of the desired product was started by scraping.
