The preparation of methyl (+) - (S) -alpha - (o-chlorophenyl) -6,7 -dihydrothiopheno (3,2 -c) pyridine-5 (4H) -acetate is an important task in organic synthesis. This synthesis method needs to be achieved in reasonable steps according to the principles of organic chemistry.
The first to bear the brunt is to find suitable starting materials. It is a common idea to start with o-chlorobenzaldehyde and corresponding compounds containing thiophenopyridine structures. O-chlorobenzaldehyde can be obtained by the chlorination of benzaldehyde. This chlorination reaction requires fine control of reaction conditions, such as temperature and catalyst dosage, to ensure that chlorine atoms are precisely substituted in ortho-sites.
