摘要:
(R)—N-benzyl-2-(benzyloxycarbonylamino)-3-methoxypropionamide is an intermediate useful for preparing lacosamide. It can be prepared, for example, by combining (R)—N-benzyl-2-(benzyloxycarbonylamino)-3-hydroxypropionamide with dimethylsulfate, followed by mixing with an alkali or alkaline earth metal hydroxide at a temperature of about 25° C. to about −15° C.
摘要:
The present disclosure relates to an improved process for the preparation of enantiomerically enriched alcohols of Formula (I), from the corresponding ketone of Formula (II), by asymmetric transfer hydrogenation, using a hydrogen donor, catalyzed by a ruthenium or rhodium complex of an optically active N-sulfamoyl-1,2-diamine. R is as defined herein.
摘要:
This invention relates to methods of making O-desmethylvenlafaxine from venlafaxine. In the methods venlafaxine is contacted with a polythiolate. The polythiolate may be prepared from the corresponding polythiol in the presence of base. The present methods provide the O-desmethylvenlafaxine in good yields and high purity and are suitable for use on an industrial scale.
