The title compound was prepared in accordance with the general method of Example 1, from 2,4-dichloropyrimidine (200 mg, 1.34 mmol) and 2-(but-3-ynyl)benzo[d]oxazole (230 mg, 1.34 mmol, Example 8(A)) at room temperature. The crude residue was purified by flash chromatography (cyclohexane/AcOEt 9:1) to yield 35 mg (0.12 mmol, 9%) of 2-(4-(2-chloropyrimidin-4-yl)but-3-ynyl)benzo[d]oxazole as a yellow solid.
