Reaction Steps

A solution of 4 (0.275 g, 1.19 mmol), 5 (0.403 g, 1.19 mmol), prepared according to Step-1 of Example 20, Pd(OAc)2 (0.0026 g, 0.11 mmol), BINAP (0.0037 g, 0.059 mmol) and Cs2CO3 (0.969 g, 2.95 mmol) in degassed toluene (toluene was purged with N2 for 30 min) was heated at 110° C. for 16 h under N2 atmosphere. The reaction mixture was cooled, diluted with EtOAc (20 mL), washed with water (10 mL), brine (10 mL) and dried over Na2SO4. Filtration followed by concentration under reduced pressure offered a residue which was further purified by column chromatography (SiO2, 60-120, pet ether/ethyl acetate 5/5) to give 6 (0.350 g, 55%) as a yellow solid.
