An efficient method is described for the preparation of molnupiravir (EIDD-2801) an antiviral agent via regioselective conversion of an N-acyl-nucleoside intermediate, generated through stereo and regioselective glycosylation of protected ribose and N 4-acetyl cytosine, to an amidoxime. This method avoids use of expensive starting materials, enzymes, complex reagents, and cumbersome purification procedures.
