実験手順

2-{[(3-tert-Butoxycarbonylamino-pyridin-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amino]-methyl}-5-cyano-benzoic acid methyl ester (0.4532 g, 0.86 mmol) was dissolved in dry THF (5 mL) and flushed with Ar. At 0° C., 1.0 M LiAlH4 in THF (8.6 mL, 8.6 mmol) was added dropwise to the solution and was stirred at room temperature for 6 hours. The reaction was cooled to 0° C. and saturated aqueous KNa Tartrate (Rochelle's salt, 10 mL) was added slowly, and then CH2Cl2 (100 mL) was added. The phases were separated and the aqueous phase was extracted with CH2Cl2 (8×75 mL). The organic extracts were dried (Na2SO4) and concentrated. Purification of the crude material by column chromatography on silica gel (20:1:1 CH2Cl2-MeOH—NH4OH) provided 0.1620 g (37%) of (2-{[(4-aminomethyl-2-hydroxymethyl-benzyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amino]-methyl}-pyridin-3-yl)-carbamic acid tert-butyl ester as a yellow solid. 1H NMR (CDCl3) δ 1.54 (s, 9H), 1.62 (s, 6H), 1.97-2.06 (m, 1H), 2.25-2.26 (m, 1H), 2.69-2.82 (m, 2H), 2.95-2.97 (m, 1H), 3.62-3.72 (m, 1H), 3.80 (s, 2H), 3.85-3.99 (m, 3H), 4.22-4.26 (m, 1H), 4.48-4.52 (m, 1H), 7.08-7.23 (m, 4H), 7.39-7.37 (m, 1H), 8.17-8.19 (m, 1H), 8.45-8.51 (m, 1H), 8.65-8.69 (m, 1H), 9.41-9.44 (m, 1H). Deprotection with TFA using General Procedure F gave COMPOUND 406 as a white solid. 1H NMR (CDCl3) δ 1.64-1.68 (m, 4H), 2.02-2.13 (m, 2H), 2.17-2.26 (m, 1H), 2.64-2.69 (m, 1H), 2.77-2.88 (m, 1H), 3.61-3.69 (m, 3H), 3.82-3.88 (m, 3H), 4.06 (d, 1H, J=12.9 Hz), 4.18 (d, 1H, J=11.1 Hz), 4.58 (d, 1H, J=11.4 Hz), 4.92 (s, 2H), 6.93-6.96 (m, 1H), 6.99-7.04 (m, 1H), 7.06-7.10 (m, 1H), 7.13-7.16 (m, 1H), 7.22-7.29 (m, 2H), 7.37 (d, 1H, J=7.5 Hz), 7.91 (d, 1H, J=3.9 Hz), 8.35 (d, 1H, J=3.9 Hz). 13C NMR (CDCl3) δ 19.54, 21.88, 29.55, 46.47, 54.64, 55.47, 58.18, 63.17, 122.36, 122.63, 124.08, 126.62, 130.67, 131.64, 135.21, 135.32, 137.99, 138.29, 142.08, 142.92, 143.78, 143.88, 146.91, 157.29.
