| titleOfInvention | Method of producing (s)-3-(1-cyano-1,1-diphenylmethyl)-pyrrolidine |
| abstract | The present application relates to a method of (S)-3-(1-cyano-1,1-diphenylmethyl)-pyrrolidine by reacting an (S)-1-protected-3-(sulfonyloxy)-pyrrolidine having an easily deprotectable protecting group with diphenylacetonitrile in the presence of a base to obtain an (S)-1-protected-3-(1-cyano-1,1-diphenylmethyl)-pyrrolidine and then deprotecting the obtained compound under a mild condition. According to the method of the present invention, it is possible to efficiently produce (S)-3-(1-cyano-1,1-diphenylmethyl)-pyrrolidine, which is an important intermediate in the process of producing a muscarinic receptor antagonist such as darifenacin. |
