Reaction Steps

Using General Procedure B: Reaction of {4-[(5-chloro-3-methyl-pyridin-2-ylmethyl)-amino]-butyl}-methyl-carbamic acid tert-butyl ester, isoquinoline-1-carbaldehyde and NaBH(OAc)3 in CH2Cl2 gave {4-[(5-chloro-3-methyl-pyridin-2-ylmethyl)-isoquinolin-1-ylmethyl-amino]-butyl}-methyl-carbamic acid tert-butyl ester as a light brown solid. 1H NMR (CDCl3): δ 1.29 (br, 2H), 1.41 (s, 9H), 1.50 (br, 2H), 2.01 (s, 3H), 2.59 (t, 2H, J=7.0 Hz), 2.68 (s, 3H), 3.02 (br, 2H), 3.78 (s, 2H), 4.19 (s, 2H), 7.35 (s, 1H), 7.45 (t, 1H, J=7.0 Hz), 7.55 (d, 1H, J=7.0 Hz), 7.62 (t, 1H, J=7.0 Hz), 7.78 (d, 1H, J=7.0 Hz), 8.05 (d, 1H, J=7.0 Hz), 8.29 (s, 1H), 8.42 (d, 1H, J=5.8 Hz). Deprotection with TFA using General Procedure F gave N-(5-chloro-3-methyl-pyridin-2-ylmethyl)-N-isoquinolin-1-ylmethyl-N1-methyl-butane-1,4-diamine.
