Reaction Steps

A mixture of POPd1 catalyst (CombiPhos Catalysts, Inc) (2 mg), (1R)-1′-{[1-(4-bromophenyl)cyclopropyl]-carbonyl}-3H-spiro[2-benzofuran-1,3′-pyrrolidin]-3-one (15 mg, 0.036 mmol), 4-vinylpyridine (19 mg, 0.18 mmol), potassium carbonate (5.5 mg, 0.04 mmol) in N,N-dimethylformamide (0.3 ml) was microwave irradiated at 135° C. for 30 minutes. Then the desired product was obtained from the mixture by prep-HPLC followed by chiral HPLC (13 mg, 82%). LCMS: m/z 437.2 (M+H)+; 459.2 (M+Na)+.
