Procedure
To a solution of 158 (0.165 g, 0.336 mmol) in DME (1.5 mL) and water (0.5 mL) was added 159 (0.107 g, 0.336 mmol), sodium carbonate (0.107 g, 1.009 mmol) followed by Pd(Ph3P)4 (0.025 g, 0.022 mmol). The reaction mixture was degassed with nitrogen and heated to 80° C. for 16 hours. After the usual work-up the crude material was purified by silica gel chromatography (Biotage 25M, 20 to 30 to 50% ethyl acetate in hexanes) to give 160 (97.7 mg, 0.163 mmol, 48.3% yield) as yellow crusty solid. LRMS (ESI): (calc.) 600.7 (found) 601.5 (MH)+.
