A mixture of intermediate (9) (0.0658 mol) in NH3/CH3OH 7N (60 ml) was stirred at 120° C. for 12 hours in an autoclave. The solvent was evaporated till dryness. The residue was taken up in 2-propanone. The precipitate was filtered off and dried, yielding 8.6 g 5,6,7,8-tetrahydro-3-nitro-2-quinolinamine (intermediate 10). d) A mixture of intermediate (10) (0.031 mol) in methanol (100 ml) was hydrogenated at room temperature under a 3.105 Pa (3 bar) pressure for 30 minutes in a Parr apparatus. After uptake of hydrogen (3 equivalents), the catalyst was filtered through celite, rinced with methanol and the filtrate was evaporated till dryness. The product was used with further purification, yielding 5.07 g 5,6,7,8-tetrahydro-2,3-quinolinediamine (intermediate 11).
