A Study and Identification of Potential By-Products of Sibutramine
摘要:
In the synthesis and process development of sibutramine (9), the isolation and characterization of two potential by-products namely heptane dinitriles (4a-b) and bis-cyclobutyl alkylamine (10) have been studied, The key steps in the synthesis of sibutramine which have contributed to the formation of above by-products are cycloalkylation of 4-chlorophenyl acetonitrile (1) and tandem Grignard reduction on 1-(4-chlorophenyl) cyclobutyl carbonitrile (3).
