PROCEDURE

实验过程

To a solution of methylenetriphenylphosphorane (14.4 mmole) in dimethyl sulfoxide (30 ml) prepared in the usual fashion was added a solution of 17-cyclobutylmethyl-3-methoxy-8β-methyl-morphinan-6-one. The reaction was heated at 75° for 2 hours under an atmosphere of nitrogen. Workup followed by chromatography gave the free base of TR-5377 as a foam. This was converted to the HCl salt which was crystallized from toluene to give 860 mg (37%) of TR-5377, mp. 221°-224°.
