盐酸多奈哌齐Chemical Name: (?-1-Benzyl-4-(5,6-dimethoxy-1-oxoindan-2-ylmethyl)piperidine hydrochloride; (?-2-(1-Benzylpiperidin-4-ylmethyl)-5,6-dimethoxyindan-1-one hydrochloride
CAS No. 120011-70-3, 123958-79-2 ([2-14C]-labeled), 142057-77-0 (deleted CAS), 120014-06-4 (free base)
项目整合开发状态: Launched-1997
项目研究机构: Eisai (Originator), National Institute of Mental Health (Not Determined), Bracco (Licensee), Pfizer (Licensee)
合成路线:The condensation of 5,6-dimethoxy-1-indanone (I) with 1-benzylpiperidine-4-carboxaldehyde (II) by means of butyllithium and diisopropylamine in THF gives 1-benzyl-4-(5,6-dimethoxy-1-oxoindan-2-ylidenemethyl)piperidine (III),which is reduced with H2 over Pd/C in THF and treated with HCl in dichloromethane - ethyl acetate.
