method for preparing pharmaceutical preparations with spasmolytische effect, thus formed pharmaceutical preparations.and method for preparation of 3 - (di - (2 - thienyl) methylideen) - n - methylpiperidinederivaten.

摘要

Di-(2-thienyl)-(N-methyl-5-methoxy-3-piperidyl)-carbinol is dehydrated. Di-(2-thienyl)-(N-methyl-5-methoxy-3-piperidylidine-methane is produced. The resultant di-(2-thienyl)-(N-methyl-5-methoxy-3-piperidylidene)-methane is reacted with a compound of the formula R-X, wherein R is lower alkyl and X is an anionic residue of a pharmaceutically acceptable acid. A compound having the formula WHEREIN X and R are as defined above, is produced. This compound is a potent antispasmodic.
