Reaction Steps

A mixture of 3-bromo-1-cyclopentyl-4-methoxy-4,5-dihydro-1H-pyrrolo[3,2-c]pyridine-7-carbonitrile (250 mg) obtained in Step H of Example 33, (4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-thienyl)acetonitrile (292 mg), tetrakis(triphenylphosphine)palladium(0) (90 mg), 2M aqueous sodium carbonate solution (0.781 mL) and DME (3.0 mL) was stirred overnight at 80° C. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (220 mg).
