Reaction Steps

A mixture of 7.40 g of 3-(benzylsulfanyl)aniline from Preparation No. 28 and 7.70 g of diethyl ethoxymethylene malonate is heated at 135° C. under a gentle flow of argon for 2 h, then diluted with 30 mL of diphenyl ether and heated to 260-270° C. After 45 min, the solution was added to 500 mL of stirred heptane. The resulting solid was filtered, washed well with hexane, and dried under vacuum to afford 8.32 g of the title compound.
