実験手順
The title compound was prepared in accordance with the general method of Example 1, from 2-iodopyridine (89 mg, 0.43 mmol) and 2-(but-3-ynyl)benzo[d]oxazole-5-carbonitrile (100 mg, 0.51 mmol) at room temperature. The crude residue was purified by flash chromatography (DCM/MeOH 99:1) to yield 45 mg (0.16 mmol, 37%) of 2-(4-pyridin-2-yl)but-3-ynyl)benzo[d]oxazole-5-carbonitrile as a brown solid.
