Reaction Steps
By the reaction of 20.0 g of γ-picolin and 26.2 g of p-hydroxybenzaldehyde in 65.8 g of acetic anhydride, there was obtained 4-[2-(4-hydroxyphenyl)-ethenyl]-pyridine. In 10 cm3 of N,N-dimethylacetamide, 2 g of the reaction product was dissolved and 1.23 g of triethylamine was further added thereto. This mixture was ice cooled and 1.34 g of methacrylic acid chloride was dropwise added thereto. After the reaction was completed, water was added to deposit crystals, which were separated by filtration. The separated crystals were recrystallized via a mixed solvent of ethyl acetate and hexane, to afford 2.16 g (80% in yield) of 4-[2-(4-methacryloyloxyphenyl)-ethenyl]-pyridine. The melting point of the crystals was 156° to 158° C.
