Reaction Conditions:

with PEG-400 in dichloromethane;acetone at 20; for 2 h;

Steps:

General procedure: To a solution of benzoyl chloride (0.23 mL, 2 mmol) in CH2Cl2 (15 mL) and acetone (15 mL), KSCN(0.2 g, 2 mmol) was added at room temperature utilizing a few drops of PEG-400 as catalyst and thereaction mixture was stirred for additional 2 h. The mixture was filtrated and the filtrate was evaporatedunder reduced pressure to give benzoyl isothiocyanate (5). To a solution of 3 (1.2 g, 2 mmol) in CH2Cl2,triethylamine was added dropwise until the solution was clarified, and 6 was prepared by treating thesolution with benzoyl isothiocyanate at room temperature. The solvent was eliminated under reducedpressure to afford a crude product which was purified by column chromatography using EtOAc andpetroleum ether as the eluent.
