Procedure

A mixture of 4.38 g (12.8 mmole) of (E)-4-carboxy-4′-[6-hydroxyhexyloxy]stilbene (16), 1.87 g (15.4 mmole) of N,N-dimethylaniline, 1.38 g (15.4 mmole) of acryloyl chloride, 8 mg of 2,6-di-t-butyl-4-methylphenol and 9 ml of 1,4-dioxane was heated at 60° C. under a nitrogen atmosphere. After 3 hours the mixture was cooled and 10 ml of 1,4-dioxane were added. The product was collected on a filter and washed with 40 ml of ethanol. 3.6 g of product (71%) were obtained after drying over silica in a dessicator.
