PROCESS FOR PREPARING OPTICALLY ACTIVE 2,3-DIHYDRO- BENZOFURAN COMPOUNDS |
摘要 |
A process for preparing optically active 2,3-dihydrobenzofuran compounds which comprises subjecting a 2,3-dihydrobenzofuran compound represented by the general formula or a salt thereof to optical resolution with an optically active acid compound: <CHEM> Äwherein R<1> and R<2> are each hydrogen or an optionally substituted hydrocarbon group; R<3> is an optionally substituted aromatic group; and C is a benzene ring which may further have a substituent in addition to the amino groupÜ. The process enables industrially advantageous production of intermediates for the synthesis of optically active 2,3-dihydrobenzofuran compounds useful as preventive and/or therapeutic drugs for neurodegenerative diseases and so on.
