Reaction Conditions

Reaction Steps

11.6 of 1,6-diaminohexane are heated, under nitrogen, to 175° C. Then 0.2 g of acetic acid are added. Over 1 hour, 68.9 g of methyl 3-(3,5-dicyclohexyl-4-hydroxyphenyl)propionate are added to this mixture. The reaction mixture is heated for a further 3 hours at 175° C. The mixture is stirred, in a mixer, with 100 ml of 1% aqueous sodium bicarbonate. The resultant solid is isolated by suction filtration and washed with water until neutral. After drying, 60.3 g of a colourless powder with a melting point of 28° C. are obtained.
