実験手順

A solution of Intermediate 5B (100 g, 324.4 mmol) in ACN (1000 mL) was degassed with N2. TEA (64 mL) and methyl acrylate (60 mL) were added and the reaction was further degassed. Pd(OAc)2 (8 g, 11.8 mmol) was added and the reaction was heated to 85° C. for 18 h. The reaction was concentrated and the residue was diluted with H2O. The aqueous layer was extracted with EtOAc and the combined organics were washed with brine. Purification by silica gel chromatography gave 25 g of Intermediate 5C. MS (ESI) m/z: 283.0 (M+H)+.
