Versuchsvorschrift
When 5 g of S-allylcysteine (0.031 mole), 1.24 g of sodium hydroxide (0.31 mole) and 4.19 g of phenylisothiocyanate (0.031 mole) were reacted according to the procedure for the preparation of the compound of Example 2, 8.59 g of crude product was obtained which did not require purification by chromatography. Crystallization of the crude product from isopropyl alcohol gave pure title compound: RF on silica gel=0.44 [ethyl acetate-hexane (2:3)].
