실험 절차

The title compound was prepared in accordance with the general method of Example 1, from 2-bromopyridine (92 mg, 0.58 mmol) and 2(but-3-ynyl)oxazolo[5,4-b]pyridine (100 mg, 0.58 mmol). The crude residue was purified by flash chromatography (DCM/MeOH 98.5:1.5 to 98:2) to yield 56 mg (0.22 mmol, 39%) of 2-(4-pyridin-2-yl)but-3-ynyl)oxazolo[5,4-b]pyridine as a colorless oil.
