Versuchsvorschrift

A stirring solution of 3.5 g. (0.014 mole) of 4-phenyl-3-methylthioindolin-2-one in 75 ml. of tetrahydrofuran was treated portionwise with 20 g. of a commercial Raney nickel/water suspension. The mixture was filtered through Celite and the filtrate was concentrated to give a yellow solid. The solid was recrystallized to give a yellow solid. This solid was recrystallized from benzene to yield 1.6 g. (57%) of product as an off-white solid. An analytical sample was prepared from isopropanol; m.p. 192°-194° C.
