A solution of Example 171a (0.158 g, 0.29 mmol), 1-(phenylsulfonyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.100 g, 0.29 mmol), catalytic amount of [1,1′-bis(diphenylphosphino)ferrocene]-dichloropalladium(II), complex with dichloromethane (1:1) and saturated sodium bicarbonate solution (2 mL) in 8 mL dimethylformamide was heated at 65° C. for 2 hours. The material was cooled to room temperature, diluted with ethyl acetate, washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified on silica gel using flash chromatography (20% ethyl acetate/hexane) to afford 0.11 g of the title compound. m/z 673.6 (ESI, M+H)+.
