Procedure

The Raney Nickel was prepared as an aqueous slurry after removing four fifth of water of the commercial solution. Aqueous Raney nickel (10 ml) was added to a solution of compound 15 (4.06 g, 13.8 mmol) in 40 ml of distilled THF and the mixture was further vigourously stirred at room temperature. When no starting material was detected by thin layer chromatography, the mixture was diluted with THF and filtered through a Celite pad. After removal of the solvent, the crude material was purified by silica gel chromatography (CH2Cl2/MeOH 95/5 then 90/10), and the solvent was evaporated to yield the 2-(5-methyl-2-oxo-2,3-dihydro-1H-indol-1-yl)acetamide 24 as a white solid.
