Reaction Steps

1.191 g of O-(p-toluenesulfonyl)-p-(2-thienylcarbonyl)mandelonitrile was dissolved in 5 ml of DME, and the solution was stirred in an argon atmosphere under ice cooling. Sodium salt of 2-mercaptobenzothiazole (567 mg) was added, and the mixture was stirred under ice cooling for 45 minutes, and then at room temperature for 30 minutes. Water (30 ml) was added, and the mixture was extracted with 30 ml of methylene chloride three times. The extract was washed with 20 ml of water, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was separated by column chromatography (silica gel; methylene chloride) to afford 788 mg (yield 67%) of alpha-(2-benzothiazolylthio)[p-(2-thienylcarbonyl)phenyl] acetonitrile as a viscous oil.
