Procedure

Place pyridinium dichromate (0.75 g, 2 mmol) and methylene chloride (15 mL) under argon atmosphere and cool to 0° C. Add α-[(2-thiophenyl)ethynyl]-benzenemethanol (321 mg, 1.5 mmol). Stir overnight while slowly warming to room temperature. Dilute with ethyl ether and filter the chromium salts. Purify by silica gel chromatography to give the title compound.
