実験手順

Iodine is added to a solution of 100 g of potassium iodide in 500 ml of water to saturation. This saturated solution is added dropwise to a solution of α-mercapto-β-(2-furyl)acrylic acid in 500 ml of acetonitrile and 30 ml of water until the color of iodine persists. The crude product which precipitates is recrystallized from methanol. M.P. 215° C.
