The present invention relates to a crystalline form of (+)-Cibenzoline succinate. The present invention is also related to a process for the preparation of (+)-Cibenzoline succinate with chiral purity greater than 99.9%. The present invention also provides a process for the preparation of (+)-Cibenzoline succinate and a crystalline form thereof.
We have developed an efficient chemical resolution of racemic hydroxy substituted dithia-aza[4]helicenes (DTA[4]H) 1(OH) using enantiopure acids as resolving agents. The better diastereomeric separation was achieved on esters prepared with (1S)-(−)-camphanic acid. Subsequent simple manipulations produced highly optically pure (≥ 99% enantiomeric excess) (P) and (M)-1(OH) in good yields. The role of
