実験手順

A mixture of N—((S)-6-bromo-1,2,3,4-tetrahydronaphthalen-2-yl)-N-methyl-5-cyclopropylmethoxypyridine-2-carboxamide (1.50 g), tributylvinyltin (1.37 g), palladium(II) acetate (16 mg), triphenylphosphine (76 mg), diisopropylethylamine (8.5 ml) and DMF (20 ml) was heated to 100° C. for 12 hours. The cooled reaction mixture was partitioned between ethyl acetate and sodium carbonate solution. The organic phase was dried over sodium sulfate, filtered and concentrated. The residue was purified by chromatography on silica gel. The product was thus obtained with the molecular weight of 362.48 (C23H26N2O2); MS (ESI): 363 (M+H+).
