19.4 g (0.1 mole) of dimethyl terephthalate and 18.5 g (0.1 mole) of dodecylamine are refluxed in 100 ml of methanol. After addition of 9 g (0.05 mole) of sodim methylate (30% strength in methanol) refluxing is continued for 8 hours, and the reaction batch is then worked up as described in Example 1, affording 31.7 g (91.2%) of 4-carbomethoxybenzoic acid dodecylamide having a 14% terephthalic acid bisdodecylamide content.
