Reaction Conditions

Reaction Steps

To a solution of 0.5 g (1.6 mmol) of material from Example 27, 0.3 g (2.3 mmol) of thiophene-2-boronic acid and 0.3 g (2.3 mmol) of potassium carbonate in 7 mL of dioxane and 2 mL of water was added 0.1 g (0.1 mmol) of tetrakis(triphenylphosphine)palladium (0). The mixture was heated to 100° C. for 16 hours cooled to ambient temperature, diluted with 5 mL of water and extracted three times with 5 mL each of ethyl ether. The combined organics were dried (MgSO4), filtered and concentrated in vacuo. The residue was recrystallized from ethyl ether, filtered and dried in vacuo to afford 0.2 g (47%) of the title compound.
