실험 절차

A stirred solution of 8 g. (0.027 mole) of 7-benzoyl-3-methyl-3-methylthioindolin-2-one in 80 ml. of tetrahydrofuran was treated under N2 with 40 g. of a commercial Raney nickel-water mixture over a 2 hr. period. At the end of this period the mixture was filtered and the residue washed thoroughly with tetrahydrofuran. One drop of concentrated hydrochloric acid was added to the filtrate and the dark orange solution turned pale yellow. The solution was stripped under vacuum to a yellow oil which crystallized on seeding. The material was recrystallized from toluene petroleum ether to give a white crystalline material. The solid (6.0 g., 89% yield) melted at 125°-127°C.
