509 mg of 1-[3-chloro-5-[2-(trifluoromethyl)cyclopropyl]-2-pyridyl]cyclopropanecarbonitrile (step 2) was dissolved in 35 ml of methanol containing 2 ml of ammonia (7N in methanol). The solution was hydrogenated over Raney-nickel (flow: 1 mL/min, 50° C., 40 bar). Then the solvent was removed at reduced pressure to give 455 mg of [1-[3-chloro-5-[2-(trifluoromethyl)cyclopropyl]-2-pyridyl]cyclopropyl]methanamine as an orange oil. 1H-NMR (CDCl3): 8.30 ppm (s, 1H), 7.87 ppm (s, 1H), 2.94 ppm (s, 2H), 2.33 ppm (m, 1H), 1.85 ppm (m, 1H), 1.78 ppm (s, 2H, broad), 1.46 ppm (m, 1H), 1.22 ppm (m, 1H), 1.00 ppm (m, 2H), 0.90 ppm (m, 2H).
