27. The synthesis of 9 has been reported: Q. Wei, and E. Galoppini Tetrahedron 60 2004 8497 Compound 9 was contaminated by 1-phenyl-3,5,7-tris(4- carbomethoxyphenyl)adamantane, which was easily separated from 2 after the cross-coupling step. The yield of 9 is dependent on the reactions conditions as the solvent and the apparatus must be rigorously anhydrous
