8-甲氧基-喹啉-5-甲酸Chemical Name: N-(3,5-Dichloro-4-pyridinyl)-8-methoxyquinoline-5-carboxamide
CAS No. 199871-63-1, 199871-80-2 (diHBr), 199871-79-9 (diHCl)
项目整合开发状态: Phase I
项目研究机构: Celltech (Originator), Schering-Plough (Codevelopment)
合成路线:8-Methoxyquinoline-5-carboxylic acid (III) was prepared by Skraup synthesis from 3-amino-4-methoxybenzoic acid (I) and glycerol (II) in sulfuric acid at 180 C.Subsequent treatment of (III) with oxalyl chloride using a catalytic amount of DMF gave the corresponding acid chloride (IV),which was finally coupled with 4-amino-3,5-dichloropyridine (V) in the presence of NaH in DMF to provide the target amide.
