Stage #1: With sodium In toluene at 65 - 70℃; for 2 h;
Stage #2: at 5 - 10℃; for 1 h;
Stage #3: at 70 - 75℃; for 5 h;
In 100ml reaction flask was added toluene 32g, 3.45g of sodium metal particles (0.15mol), stirring, dropping 6.9g ethanol (0.15mol) dropwise, the process of maintaining the temperature at 65 ~ 70 ° C.Dropping end, stirring 2h, the reaction system was added dropwise phenylphosphine chloride 33. lg (0.15mol), the control temperature 5 ~ 10 ° C, the dropwise addition is complete,Stirring 1h, continue to the reaction system dropwise 2,4,6-trimethylbenzoyl chloride 30.1g (0.16mol), the dropping temperature was controlled at 70 ~ 75 ° C, and then stirred for 5h. The reaction was completed, the reaction material was added 15g of water, stirred lh, standing stratification, the resulting organic phase was adjusted to a saturated aqueous sodium bicarbonate solution pH 7 ~ 8, points to the aqueous phase, the organic phase was washed with water ,The resulting organic phase was dehydrated, cooled and crystallized, filtered,Dried to give a pale yellow powdery solid 48.2g, melting point 91 ~ 94 ° C, the liquid content of 99.3percent, a yield of 92.2percent
