4-Bromo-2-methyl-1,3-thiazole → 2-(4-(2-Methylthiazol-4-yl)but-3-ynyl)benzo[d]oxazole

Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 1, from 4-bromo-2-methylthiazole (47 mg, 2.7 mmol) and 2-(but-3-ynyl)benzo[d]oxazole (454 mg, 2.65 mmol, Example 8(A)). The reaction mixture was stirred for one day under reflux. The crude residue was purified by flash chromatography (cyclohexane/AcOEt 4:1) and trituration with pentane to yield 14 mg (52 μmol, 2%) of 2-(4-(2-methylthiazol-4-yl)but-3-ynyl)benzo[d]oxazole as a beige solid.
