Participants

Reaction Steps

4 g of (S)-2-(2-naphthylsulonylamino)-3-phenyl-propionic acid are dissolved in 40 ml of anhydrous benzene-anhydrous tetrahydrofuran (3:1), and 3.2 ml of thionyl chloride are added thereto. The mixture is stirred at 40° to 50° C for 18 hours. The reaction mixture is condensed to dryness under reduced pressure, and the residue is recrystallized from a mixture of benzene and n-hexane. 3.2 g of (S)-2-(2-naphthylsulfonylamino)-3-phenyl-propionyl chloride are obtained.
