Conditions

Temperature: 80 °C

Procedure

A mixture of ester from step 2 (1.7 eq), dibromo from step 1 (1 eq), Pd2(dba)3 (0.05 eq) and triphenylarsine (0.25 eq) in DMF (0.05M) was heated at 80° C. for 2 h. The mixture was cooled to rt, diluted with EtOAc and water, the organic was washed with brine, dried and solvent evaporated. The residue was purified by flash chromatography (CH2Cl2:MeOH; 99:1 to 90:10) to afford the title compound.
