Procedure

Using Method C above, (R)-3-Hydroxy-1-prop-2-ynyl-pyrrolidine (60 mg, 0.48 mmol) (Example 92A) was coupled with (Z)-1,3-dihydro-5-fluoro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (60 mg, 0.16 mmol) (Starting Material 6) using (Ph3P)4Pd (18 mg, 0.02 mmol) and a catalylic amount of CuI in a mixture of DMF (4 mL) and Et3N (4 mL) as solvent at 80° C. for 6 hrs. Upon completion, the reaction mixture was diluted with EtOAc and extracted with H2O. The organic layer was dried over Na2SO4 and concentrated. (R)-(Z)-1,3-Dihydro-5-fluoro-4-[3-(3-hydroxy-pyrrolidin-1-yl)-1-propynyl]-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one was obtained after silica gel column chromatography with a 0-20% MeOH in CH2Cl2 gradient and precipitation out of THF with excess of pentane. (Yield 45 mg, 76%).
