Reaction Steps

A solution of 1,1-dimethylethyl 3-methyl-4-oxo-1-piperidinecarboxylate (367 mg, 1.72 mmol) in THF (10 mL) was treated with methylhydroxylamine hydrochloride (503 mg, 6.02 mmol) followed by a solution of sodium hydrogencarbonate (506 mg, 6.02 mmol) in water (3 mL). The reaction was stirred vigorously overnight. The reaction was then filtered, diluted with water, and extracted with dichloromethane. The crude material was purified by column chromatography (0-10% ethyl acetate/hexanes) to provide 197 mg of the desired product as a white solid. 1H NMR (400 MHz, CDCl3) δ ppm 1.1 (d, J=6.8 Hz, 3H), 1.5 (s, 9H), 2.5 (m, 1H), 2.6 (m, 2H), 3.5 (m, 4H), 3.8 (s, 3H).
