A Process for preparing linezolid and its intermediate
-
Paragraph 0075-0080, (2018/02/14)
The present invention relates to a manufacturing method of linezolid which is an oxazolidinone-based antibiotic. More specifically, the present invention relates to a novel manufacturing method of linezolid; and to an intermediate compound of linezolid, and the manufacturing method of linezolid uses a novel halomethyl ethanone compound as an intermediate for the manufacture of linezolid, thereby simplifying a manufacturing process and reducing manufacturing costs in comparison with a conventional manufacturing method. The intermediate compound is a novel compound, and is an (S)-1-(5-(halomethyl)-2, 2-dimethyl oxazolidine-3-yl)ethanone compound represented by chemical formula 1. In chemical formula 1, R is one element selected from F, Cl, Br, and I. The manufacturing method of linezolid comprises: a step (A) of performing a reaction process of a compound represented by chemical formula 1 and a compound represented by chemical formula 2 to manufacture a compound represented by chemical formula 3; a step (B) of hydrolyzing the compound represented by chemical formula 3 to obtain a compound represented by chemical formula 4; and a step (C) of performing carbonylation of the compound represented by chemical formula 4.COPYRIGHT KIPO 2016

A series of novel oxazolidinone derivatives bearing fluoroalkyl-substituted pyrazole as the C-ring structure were designed, synthesized and evaluated for their antibacterial activity against six Gram-positive bacterial pathogens. Most of the target compounds have good antibacterial activity. Especially, compounds 13f, 13i and 13l show excellent activity comparable to linezolid.
