Procedure

3-Chloro-5,6,7,8,9,10-hexahydrocycloocta[c]pyridazine (1.36 g) was treated with anhydrous pyridine (10 mL) and anhydrous hydrazine (3 mL) at 100° C. for 5.5 h. The solvent was removed under vacuum and the residue was partitioned between chloroform and saturated aqueous potassium carbonate solution. The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum to provide 3-hydrazinyl-5,6,7,8,9,10-hexahydrocycloocta[c]pyridazine; 1H NMR (CDCl3, 300 MHz) 6.71 (s, 1H), 3.01 (m, 2H), 2.68 (m, 2H), 1.70-1.85 (m, 4H), 1.40 (m, 4H) ppm; MS (ES) 193 (M+H).
