実験手順

To a stirred solution of methyl (2S)-2-({[(1,1-dimethylethyl)oxy]carbonyl}amino)-4-pentynoate (D64, 365 mg, 1.60 mmol), prepared with analogous procedure to that described hereinabove, N-[(2-fluorophenyl)methyl]-4-iodoaniline (D63, 630 mg, 1.92 mmol) and diethylamine (0.82 ml, 585 mg, 8 mmol) was added CuI (30 mg, 0.08 mmol) and PdCl2(PPh3)2 (56 mg, 0.08 mmol). After stirring at room temperature for 5 h ethyl acetate was added and the solution was extracted with sat. ammonium chloride solution. The organic layer was dried (Na2SO4), filtered and evaporated. The resulting crude material was purified by flash chromatography using a cyclohexanes, ethyl acetate gradient (5%40%) on silica gel to afford the title compound (192 mg, 28%); UPLC: 0.88 min, MS: (ES/+) m/z: 427 [MH]+, C24H27FN2O4 requires 426.
