  • PROCESS FOR PREPARING (R)-N-BENZYL-2-(BENYLOXYCARBONYLAMINO)-3-METHOXYPROPIONAMIDE
    Publication number: 20100240926
    Abstract: (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.

  • Method for preparation of o-desmethylvenlafaxine using polythiolates
    Publication number: 20100016638
    Abstract: 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.
