Procedure

Using Method C above, 4R-(1R-Hydroxy-prop-2-ynyl)-2,2,5R-trimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (0.2 g, 0.65 mmol) (Example 105A above) was coupled with (Z)-1,3-dihydro-5-fluoro-4-iodo-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2H-indol-2-one (0.1 g, 0.26 mmol) (Starting Material 6) using (Ph3P)4Pd (30 mg) and Cul (6 mg) as catalyst in DMF (5 mL) and Et3N (5 mL) as solvent at 85° C. for 18 h. To above compound in CH2Cl2 (10 mL) was added a 1:1 mixture of trifluoroacetic acid/CH2Cl2 (10 mL) and 5 drops of water at 0° C. and the mixture was stirred at 0° C. for 1.5 h. The mixture was then quenched with conc. NH4OH (10 mL) and diluted with EtOAc. The organic layer was washed with brine and dried with MgSO4. The product was purified via flash column chromatography (10% MeOH in CH2Cl2). (Yield 35 mg, 35%).
