4-Methoxyimino-piperidine-1-carboxylic acid tert-butyl ester in MeOH (10 mL) was treated with 4.0 M HCl/dioxane (1.0 mL) and stirred at room temperature over night. The solution was concentrated to yield 213 mg of the title compound without further purification. 1H NMR (DMSO, 300 MHz) δ ppm 2.47 (t, 2H, J=6.62 Hz), 2.68 (t, 2H, J=6.07 Hz), 3.17 (m, 4H), 3.77 (s, 3H), 9.08 (bs, 1H).
