Title:
METHOD FOR PRODUCING AMINOSTILBENE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2003/000645
Kind Code:
A1
Abstract:
A specific aminostilbene derivative or a salt thereof such as (Z)−3,4,4',5−tetramethoxy−3'−aminostilbene, which is important as an active component of an anticancer drug or an intermediate for the production of the component, can be commercially produced with good efficiency by a method comprising reacting a specific nitrostilbene derivative such as (Z)−3,4,4',5−tetramethoxy−3'−nitrostilbene with formic acid and&sol or a formate salt in the presence of a noble metal catalyst such as a platinum catalyst or a palladium catalyst, to thereby selectively reduce a nitro group alone.
