3-Hexyl-6-methyl-6-(3-nitrophenyl)-3-azabicyclo[3.1.0]hexan-2-one (Preparation 11, 6.3 g, 19.9 mmol) was dissolved in ethanol (250 ml), and iron powder (8.5 g, 0.15 mol), calcium chloride (0.95 g, 8.6 mmol) and water (50 ml) was added. The reaction mixture was refluxed for 2 h. The reaction mixture was cooled to room temperature and calcium chloride (0.95 g, 8.6 mmol) was added, the reaction mixture was refluxed for a further 16 h. The reaction mixture was cooled and filtered and then concentrated in vacuo, the residue was partitioned between dichloromethane and water and the organic layer separated, the aqueous layer was extracted with dichloromethane (3×) and the combined extracts were dried (Na2SO4) and concentrated in vacuo. The title compound was obtained as an orange solid (5.72 g, 100%).
