실험 절차

To an agitated solution of 9.7 g (0.032 mole) of 2-amino-3-benzoyl-α-(methylthio)-phenylacetamide in 100 ml of tetrahydrofuran was added 80 g of wet Raney nickel (washed 3 times with water and 3 times with tetrahydrofuran). After 10 minutes the mixture was filtered to remove Raney nickel and the filtrate concentrated under vacuum. The residue was crystallized from isopropyl alcohol to give 6.0 g (73%) of yellow needles, m.p. 178.5°-180.0° C.
