HCID 1892084911-[2,3Difluorobiphenyl-4'-yl]oxyundecyl 2,2-bis(6-acryloyloxyhexyl)acetateYield 32%

Procedure

First, 3.66 g of 11-[2,3-difluorobiphenyl-4'-yl]oxyundecyl 2,2-bis(6-hydroxyhexyl)acetate, 1.3 g of triethylamine, and 30 ml of benzene were placed in a 100 ml flask. Then, a small amount of benzene in which 1.2 g of acryloyl chloride was dissolved was added dropwise to the reaction mixture under ice water cooling. The resultant reaction mixture was allowed to warm to room temperature and stirred for 3 hours. The reaction mixture was poured into water, and an organic layer was extracted with ether. The ether layer was washed with diluted hydrochloric acid and water in this order, and then dried over anhydrous sodium sulfate. Thereafter, the solvent was distilled away. The residue was purified by silica gel column chromatography (eluent: ethyl acetate/toluene=1/20) to obtain 1.36 g of 11-[2,3difluorobiphenyl-4'-yl]oxyundecyl 2,2-bis(6-acryloyloxyhexyl)acetate (Y: 32%). The compound thus obtained was liquid at room temperature. The compound thus obtained had a purity of 99% by HPLC and of 1 spot by TLC.
