Reaction Steps

To a solution of 115 mg (0.428 mmol) 5-(3-chloro-phenyl)-1-methyl-5-nitro-piperidin-2-one in 0.5 ml dioxane was added 2 ml 3NHCl and 280 mg (4.28 mmol) zinc dust. The mixture was stirred at room temperature for 30 minutes. The mixture was filtered and the filtrate was basified with a 5N NaOH solution. Ethyl acetate was added. The mixture was filtered through a pad of dicalite. The organic layer was separated and the aqueous layer was extracted twice with ethyl acetate. The combined extracts were dried over sodium sulfate, filtered and concentrated in vacuo to provide 88 mg (86%) of the title compound as a light yellow oil. MS (m/e): 239.0 (MH+).
