After cooling, insoluble material was filtered off, and the solution thus obtained made alkaline with 200 ml of a 10 N NaOH solution, then steam distilled and the distillate collected in a 12 N HCl solution. The acidic medium was brought to dryness using 100 ml of ethanol, then 100 ml of acetone to eliminate the last traces of water. The residue was suspended in 100 ml of anhydrous acetone and after filtration, 12.8 g of 3-azabicyclo (3,3,0) octane hydrochloride was obtained, m.p.: 136-137°C, which was nitrosated with sodium nitrite, as mentioned above, for to give N-nitroso-3-azabicyclo(3,3,0) octane, b.p. / 0.1 mm Hg = 90-95°C.
