Chemical Name: 6-Chloro-1-methyl-4-oxo-7-(1-piperazinyl)-4H-[1,3]thiazeto[3,2-a]-1,8-naphthyridine-3-carboxylic acid hydrochloride
项目整合开发状态: Biological Testing
项目研究机构: Nippon Shinyaku (Originator)
合成路线:Adamantylbenzoic acid (I) was converted to acid chloride (II) on treatment with SOCl2,and subsequently condensed with allyl p-hydroxybenzoate (III) in the presence of Et3N to afford the benzoyloxybenzoic ester (IV).The allyl ester was then cleaved by refluxing in aqueous ethanol in the presence of tris(triphenylphosphine)rhodium chloride to yield the title compound.
