Yield Reaction Conditions Operation in experiment
To a solution of compound Int-lla (0.5 g, 1.58 mmol, prepared as described in U.S. Patent Publication No. US20090068140) in DME (15 mL) at room temperature under N2 was added PdCl2(dppf)2 (258 mg, 0.30 mmol). The reaction mixture was allowed to stir at 100 0C for 5 minutes, then a solution of compound Int-llb (592 mg, 3.16 mmol) and K2CO3 (654 mg, 4.74 mmol) in 15 mL H2O was added to the reaction mixture in 3 portions over 10 minutes. The resulting reaction was allowed to stir for an additional 30 minutes, after which time thin-layer chromatography analysis indicated consumption of compound Int-7a. The reaction was allowed to stir for an additional 30 minutes, then was concentrated in vacuo, and the residue obtained was taken up in 150 mL ethyl acetate. The organic phase was separated, washed with water (50 mL), brine and dried over sodium sulfate. After filtration, the organic layer was concentrated in vacuo and the resulting residue was purified using flash liquic chromatography (0% to 100% EtOAc/Hexane) to provide 600 mg of compound Int-llc (>; 85% purity, theory 597 mg). HPLC (C18 column Gemini 5u HOA, 150X21.2 mm, 5 micron). FABMS: MH+ = 379
To a solution of Compound Int-7d (0.5 g, 1.58 mmol) in DME (15 mL) at room temperature under N2 was added PdCl2(dppf)2 (258 mg, 0.30 mmol). The reaction mixture was allowed to stir at 100 0C for 5 minutes, then a solution of compound Int-19a (592 mg, 3.16 mmol) and K2CO3 (654 mg, 4.74 mmol) in 15 mL H2O was added to the reaction mixture in 3 portions over 10 minutes. The resulting reaction was allowed to stir for an additional 30 minutes, after which time thin-layer chromatography analysis indicated consumption of compound Int-7a. The reaction was allowed to stir for an additional 30 minutes, then was concentrated in vacuo, and the residue obtained was taken up in 150 niL ethyl acetate. The organic phase was separated, washed with water (50 rnL), brine and dried over sodium sulfate. After filtration, the organic layer was concentrated in vacuo and the resulting residue was purified using flash liquic chromatography (0% to 100% EtOAc/Hexane) to provide 600 mg of compound Int-19b (>; 85% purity, theory 597 mg).

Yield Reaction Conditions Operation in experiment
EXAMPLE 15 Preparation of Intermediate Compound Int-15c (0321) (0322) To a solution of compound Int-7d (0.5 g, 1.58 mmol) in DME (15 mL) at room temperature under N2 was added PdCl2(dppf)2 (258 mg, 0.30 mmol). The reaction mixture was allowed to stir at 100 C for 5 minutes, then a solution of compound Int-15b (592 mg, 3.16 mmol) and K2CO3 (654 mg, 4.74 mmol) in 15 mL H2O was added to the reaction mixture in 3 portions over 10 minutes. The resulting reaction was allowed to stir for an additional 30 minutes, after which time thin-layer chromatography analysis indicated consumption of compound Int-7a. The reaction was allowed to stir for an additional 30 minutes, then was concentrated in vacuo, and the resulting residue was taken up in 150 mL ethyl acetate. The organic phase was separated, washed with water (50 mL), brine and dried over sodium sulfate. After filtration, the organic layer was concentrated in vacuo and the resulting residue was purified using flash liquid chromatography (0% to 100% EtOAc/Hexane) to provide 600 mg of compound Int-15c (> 85% purity, theory 597 mg). HPLC (C18 column Gemini 5u 110A, 150X21.2 mm, 5 micron). FABMS: MH+ = 379
