Reaktionsschritte

17.6 g (100 mmol) of cyclohexylphenol and 19 g (106 mmol) of nicotinic acid chloride hydrochloride was mixed with 250 ml of dry pyridine and kept at 40° C. for 4 hours. Subsequently, the mixture was cooled in the ice bath, and water added in portions. After addition of 10 ml of water a clear solution was obtained. Water (50 ml) was admixed until strong turbidity appeared. After stirring the mixture for a longer period of time the product crystallized in the ice bath. The precipitate was sucked off, freed from pyridine by washing with water and dried. A second fraction was obtained from the filtrate by further adding water (60 ml).
