HCID 86711667(4bS,8R,8aR,9aR,10S,13aR,13bR)-10-tert-butyl-5,6,7,8,9,9a,10,13b-octahydro-1-methoxy-7,10-dimethyl-8a,13a-ethano-4,8-methanobenzofuro[3,2-e][1,3]dioxino[4,5-g]isoquinolineYield 81.3%

Procedure

The title compound 23 was synthesized similar to the procedure described in Example 5 for preparing compound 7 using methyl iodide rather than benzyl bromide and compound 22 rather than compound 3. After column chromatography, 168 mg (81.3% yield) of compound 23 was isolated in a purity of >99% as a white solid.
