Abstract
The present invention describes a method for the preparation of asymmetric N,N'-disubstituted cyclic ureas through the selective monodebenzylation of symmetric N,N'-disubstituted cyclic ureas using a dissolving metal reduction. The intermediates can be alkylated to give compounds which are useful as HIV protease inhibitors for the treatment of HIV infection.
