Procedure

A mixture of 9-hydroxymethylanthracene (20.8 g, 0.1 mol) and triethylamine (11.1 g, 0.11 mol), containing 0.05 g of 2,6-di-tert.butyl-p-cresol, in 200 ml of freshly distilled diethyl ether was cooled with stirring to 0° C., and the temperature of the mixture was kept at about this level while acryloyl chloride (9.32 g, 0.103 mol) was added. The mixture was then warmed to refluxing temperature and heated to reflux for 2 hours. After the mixture had been cooled, 200 ml. of water was added, and the two layers were separated. The organic layer was washed twice with 50 ml portions of cold 10% sulphuric acid and then with a saturated aqueous solution of sodium bicarbonate, while the aqueous acid layer was extracted further with dichloromethane, and the organic layer was washed with a saturated aqueous solution of sodium bicarbonate. Finally, the two organic solutions were mixed, dried over anhydrous magnesium sulphate, and the solvents distilled off. There remained 11.1 g of the title compound as a yellow, semicrystalline oil. It solidified on standing and then had m.pt. 120°-125° C.
