Procedure

A mixture of 9 (0.591 g, 2.03 mmol), 16 (0.700 g, 2.07 mmol), tetrakis(triphenylphosphine)palladium(0) (117 mg, 102 μmol), Na2CO3 (1.59 g, 15.0 mmol), H2O (15 mL) and THF (25 mL) was degassed with argon for about 20 min while stirring. The stirring reaction mixture was then maintained under argon at about 80° C. for about 19 h. Upon completion, the mixture was cooled to RT, filtered and the precipitate collected as a white solid (0.83 g, 97%). This compound was found to be insoluble in numerous common organic solvents.
