Versuchsvorschrift
A solution of 419 mg (1.4 mmol) of 1-(tert-butoxycarbonyl)-4-(1,3-dioxo-3-methoxy-2-methyl-prop-1-yl)piperidine (from Step B) and 0.26 mL (8.4 mmol) of hydrazine in 5 mL of toluene was refluxed for 50 minutes. The reaction was cooled to rt and placed in the freezer overnight. After decanting the solvent, the white solid was triturated with Et2O to provide the title compound, which was used without further purification. 1H-NMR (500 MHz) δ 1.49 (s, 9H), 1.55–1.63 (m, 2H), 1.77–1.79 (m, 2H), 1.90 (s, 3H), 2.69–2.77 (m, 3H), 4.22 (m, 2H), 5.15–5.79 (br m, 2H).
