| titleOfInvention | Method for crystallizing 4-benzyl-5-hydroxymethyloxazolidin-2-one |
| abstract | (57) [Summary] [Purpose] High concentration, high yield, and high quality (high purity) The present invention provides a method for crystallization of optically active 4-benzyl-5-hydroxymethyloxazolidin-2-one which can be crystallized in the following manner and can maintain a slurry state with good fluidity which is hard to be whipped in the subsequent reaction step. . [Structure] The crystallization solvent has at least one of a hydroxyl group, a carbonyl group, an amide bond, a cyclic ester bond, an ether bond or a cyano group in the molecule, and has another group, bond or ring with high water affinity. It is an organic solvent which does not have, and the solubility of the organic solvent in water or the solubility of water in the organic solvent is 7 w / w% at 1 atm and 20 ° C. Crystallization method of (4S, 5S) -4-benzyl-5-hydroxymethyloxazolidin-2-one or (4R, 5R) -4-benzyl-5-hydroxymethyloxazolidin-2-one using the above mixed solvent . |
