Reaction Conditions:

with potassium carbonate at 80; for 1.5 h;

Steps:

General procedure forthe formation of oxazole as illustrated by the synthesis of 5-(4-methoxyphenyl)oxazole (1)

General procedure: To a solution of p-anisaldehyde (1.22 mL, 10.0 mmol) in MeOH (25 mL) were added K₂CO₃ (1.52 g, 11.0 mmol) and TosMIC (1.08 g, 5.50mmol). The reaction mixture was stirred for 1.5 h at 80° C, cooled down to rt, quenched with H₂O, and diluted with EtOAc. After removal of the organic layer, the aqueous layer was extracted with EtOAc. The organic layer was combined, dried over Na₂SO₄, filtered, and concentrated in vacuo. Flash chromatography (3:1 hexanes/EtOAc) afforded 5-(4-methoxyphenyl)oxazole (1) (955 mg, 99%) as a pale yellow solid
