This invention relates to novel intermediate compounds which are useful for producing the halogenated protese inhibitors that are the subject matter of U.S. Patent 4,469,885. In particular, the invention relates to novel methods and intermediates for making said protease inhibitors, the intermediate compounds being of the formula:
wherein R₁ is:
(a) straight or branched chain lower alkyl having 1-6 carbon atoms; or
(b) H;
wherein R₆ is:
(a) straight or branched chain higher alkyl having 13-25 carbon atoms; or
(b) straight or branched chain higher alkenyl having 13-25 carbon atoms;
wherein R₅ is:
(a) straight or branched chain lower alkyl having 1-6 carbon atoms; or
(b) benzyl;
wherein R₇ is:
(a) straight or branched chain lower alkyl having 1-6 carbon atoms; or
(b) H;
wherein R₂ is:
(a) -Cl, Br, or -I; or
(b) -CF₃.
