Using General Procedure B, (4-amino-butyl)-cyclopropyl-carbamic acid tert-butyl ester and 3,5-dimethyl-pyridine-2-carbaldehyde in MeOH were reacted with NaBH4 to obtain cyclopropyl-{4-[(3,5-dimethyl-pyridin-2-ylmethyl)-amino]-butyl}-carbamic acid tert-butyl ester as a colorless oil (0.217 g, 89%). 1H NMR (CDCl3) δ 0.52-0.58 (m, 2H), 0.68-0.74 (m, 2H), 1.44 (s, 9H), 1.53-1.65 (m, 4H), 2.26 (s, 6H), 2.45-2.50 (m, 1H), 2.70 (t, 2H, J=6.9 Hz), 3.19 (t, 2H, J=7.2 Hz), 3.82 (s, 2H), 7.23 (s, 1H), 8.20 (s, 1H).
