Procedure

In a 750 ml sulfonating flask, 30.0 g (0.252 mol) of 4-hydroxybenzonitrile, 84.0 g (0.252 mol) of 1-bromooctadecane and 48.7 g (0.353 mol) of finely ground potassium carbonate are introduced into 200 ml of N-methylpyrrolidone (NMP) under a nitrogen atmosphere and heated at 120° C., with stirring. After being stirred for 15 hours, the mixture is cooled to room temperature and poured into 2 liters of water, whereupon a light-beige solid precipitates out, which is filtered off and washed with water. After drying at 60° C. and 150 mbar, there are obtained 90.8 g (97% of theory) of a colourless crystalline solid of formula
