実験手順

Compound 196 (0.178 g, 0.521 mmol), compound 194 (0.125 g, 0.434 mmol), and LiHMDS 1M in THF (1.30 mL, 1.30 mmol) were combined in 5 mL of anhydrous toluene. N2 was bubbled through the solution briefly before adding Pd2(dba)3 (0.0298 g, 0.0326 mmol) and 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (0.0377 g, 0.0652 mmol). The solution was then heated to 80° C. for 2 hours with microwave irradiation. The solution was diluted with DCM before it was poured into sat's NH4Cl. Partitioned the layers and washed the aqueous layer with 10% i-PrOH/DCM. The combined organics were dried over MgSO4 and then concentrated under vacuum. The residue obtained was purified on CombiFlash column (dry loaded), eluting with a gradient of 60% ethyl acetate/hexane to 100% ethyl acetate. The fractions containing the product were combined and concentrated under vacuum. The residue obtained was repurified on CombiFlash column (dry loaded), eluting with a gradient of 2% methanol/0.1% NH4OH (˜28% in water)/DCM to 4% methanol/0.2% NH4OH (˜28% in water)/DCM. The fractions containing the product were combined and concentrated under vacuum. The residue obtained was sonicated in methanol. Filtration provided an off-white solid as compound 197 (0.173 g, 72%). LCMS-ESI (POS), M/Z, M+1: Found 549.1.
