Synthesis

The synthesis of?1,4-Bis-[4-(3-acryloyloxypropyloxy)benzoyloxy]-2-methylbenzene is as follows:Stirrer, was added methanesulfonyl chloride 5.00 g (43.6 mmol) and tetrahydrofuran 10mL the reactor having a thermometer and two dropping device. Ice-cold while each by dropping a tetrahydrofuran solution 30mL of formula tetrahydrofuran solution 60mL and triethylamine 5.25g of (I-3-1) represented by the compound 12.9g (44.1 mmol) of (51.9 mmol) from device (equation (solution of the compound represented by I-3-1)) :( triethylamine solution) = 2: were added dropwise simultaneously with one of the drip rate.After stirring for 1 hour while cooling with ice, it was added 4-dimethylaminopyridine 2.64 g (21.6 mmol) and 2- (4-hydroxyphenyl) ethanol 2.69 g (19.4 mmol).With ice-cooling was added dropwise triethylamine 5.25g (51.9 mmol).After stirring for 7 hours, the solvent was distilled off and treated added for liquid separation dichloromethane and 5% hydrochloric acid.After the organic layer was washed with brine neutralization, and purified by column chromatography (silica gel) and reprecipitated (dichloromethane / methanol) to give the compound 12.2g of formula (I-3).82% yield, had a purity of 99.63%.
