Procedure

To a solution of thiazole-2-thiol (300 mg, 2.56 mmol), isopropanol (154 mg, 2.56 mmol) and triphenylphosphine (671.5 mg, 2.56 mmol) in THF (5 mL) was added DEAD (445.8 mg, 2.56 mmol) dropwise at room temperature. The mixture was stirred at room temperature for 3 hours. Reaction was completed according to t.l.c. The reaction mixture was allowed to stir over the weekend then concentrated and the residue was subjected to flash column chromatography using 10% ethyl acetate/hexane as solvent to give a colorless oil (260 mg, 64% yield).
