実験手順

To a solution of methyl 5-bromo-3-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-2-methylbenzoate (1.80 g, 5.05 mmol) and tert-butyl 4-ethynylpiperidine-1-carboxylate (1.80 g, 8.59 mmol) in DMF (40 ml) was added triethylamine (2.82 ml, 20.2 mmol) and Copper(I) iodide (0.096 g, 0.505 mmol). The reaction mixture was degassed by bubbling nitrogen for 15 min. Then tetrakis(triphenylphosphine)palladium(0) (0.292 g, 0.253 mmol) was introduced and degassed for additional 10 min by bubbling nitrogen. The reaction mixture was heated at 80° C. for 6 h. The reaction was quenched with sat. NaHCO3, extracted with TBME (3×40 mL), dried over Na2SO4, filtered and concentrated. The residue was purified by chromatography (0% to 40% AcOEt/Heptane) to give the titled compound (2.40 g, 98% yield). 1H-NMR (500 MHz) 3 ppm; 7.65 (s, 1H), 7.28 (s, 1H), 3.97 (brd, J=11.3 Hz, 2H), 3.90 (s, 3H), 3.76 (m, 2H), 3.34 (dt, J=2.0, 11.7 Hz, 2H), 3.24 (ddd, J=3.4, 8.8, 12.2 Hz, 2H), 3.08 (brs, 2H), 2.98 (brs, 1H), 2.80 (dddd, J=3.9, 3.9, 3.9, 3.9 Hz, 1H), 2.52 (s, 3H), 1.87 (m, 2H), 1.60-1.74 (m, 6H), 1.48 (s, 9H), 0.89 (t, J=6.8 Hz, 3H)); MS (ESI) [M+H]+485.4.
