실험 절차

A mixture of 4-chloro-2-(1-(5-methyl-6-(2,2,2-trifluoroethoxy)pyridin-3-yl)ethyl)-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-1-one (50 mg, 0.13 mmol, Intermediate-2, single enantiomer), phenyl formate (32 mg, 0.26 mmol, single enantiomer), palladium acetate (II) (0.87 mg, 0.039 mmol), and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (9.0 mg, 0.016 mmol) in MeCN (1.0 mL) is heated at 80° C. overnight (T. Ueda et al, Org. Lett., 2012, 14, 3100-3103). The mixture is diluted with water, and extracted with EtOAc. The organic layer is dried over sodium sulfate and filtered. The filtrate is concentrated under reduced pressure. The residue is purified by column chromatography on silica gel eluting with n-hexane/EtOAc (2:1 to 1:2) to give 45 mg (74% yield) of the title compound as off white solid.
