Abstract: A process for preparing buprenorphine of formula (I) comprises (A) oxidation of a cyan compound in 30% H2O2 soln. and NaOH soln. to form a urea cpd. (II), (B) reaction of (II) with KOH in the presence of diethyleneglycol to form a amine cpd. (III), (C) reaction of (III) with halomethylcyclopropane in the presence of K2CO3 and organic solvent, (D) reaction of the resultant cpd. with base in organic solvent to form (I). (I) is useful as an analgesic being antagonistic to narcotic addict.
