Reaction Conditions

Reaction Steps

Thionyl chloride (1.53 mL) and DMF (catalytic amount) were added to a solution of N-(5-indanyl)-3-(phenylthio)acrylamide (2.47 g) in toluene (80 mL), and the mixture was stirred at 70° C. for 1 hour. The reaction mixture was concentrated under reduced pressure. To the residue was added anhydrous THF (40 mL). To a solution of phenol (1.18 g) in anhydrous THF (20 mL) was added sodium hydride (60%) (0.769 g) under a nitrogen atmosphere under ice-cooling, and then stirred at room temperature under a nitrogen atmosphere for 30 minutes. The reaction mixture was added to the above-described reaction mixture under ice-cooling, and the mixture was stirred at room temperature for 2.5 hours. To the reaction mixture was added ethyl acetate (200 mL), which was washed with a 1N aqueous sodium hydroxide solution, water and then a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was isolated and purified by silica gel column chromatography (hexane:ethyl acetate=5:1) to obtain phenyl N-(5-indanyl)-3-(phenylthio)acrylimidate (2.56 g) as a orange oil.
