Procedure

The title compound was prepared in accordance with the general method of Example 1, from 2-bromopyridine (161 mg, 1.02 mmol) and 2-(but-3-ynyl)benzo[d]oxazole-7-carbonitrile (200 mg, 1.02 mmol). The crude residue was purified by flash chromatography (DCM/MeOH 99:1) to yield 48 mg (0.18 mmol, 17%) of 2-(4-(pyridin-2-yl)but-3-ynyl)benzo[d]oxazole-7-carbonitrile as a yellow solid (M.P.=126-126.5° C.).
