実験手順
2-(2-Propynyloxy)tetrahydro-2H-pyran (360 mg), 5-iodo-2-pyridinylamine (440 mg), CuI (140 mg) and dichlorobis(triphenylphosphine)palladium (60 mg) are dissolved in diethylamine (10 mL). After the mixture is stirred for 1 h at room temperature, water (40 mL) and CH2Cl2 (80 mL) are added. The organic laywer is separated, dried (MgSO4) and concentrated. The resulting residue is purified on a silica gel plate (CH2Cl2/methanol, 9/1) to give 230 mg (50%) of the title compound as an oil which slowly solidifies. MS (ESI+) m/z 233 (M+H)+. 1H NMR (CDCl3) δ8.10, 7.60, 6.65, 5.90, 4.86, 4.48, 3.90, 3.5-3.6, 1.55-1.9.
