Using General Procedure A: Reaction of bis-(3-methyl-pyridin-2-ylmethyl)-amine, (4-chloro-cis-but-2-enyl)-carbamic acid tert-butyl ester (Casara, P et al, J. Am. Chem. Soc. 1989, 111, 9111-9113), KI in anhydrous CH3CN and DIPEA gave {4-[Bis-(3-methyl-pyridin-2-ylmethyl)-amino]-cis-but-2-enyl}-carbamic acid tert-butyl ester. 1H NMR (CDCl3) δ 1.46 (s, 9H), 2.13 (s, 6H), 3.18 (d, 2H, J=6.0 Hz), 3.63 (t, 2H, J=6.0 Hz), 3.74 (s, 4H), 5.69 (br, 2H), 5.80 (br, 1H, (NH)), 7.08 (m, 2H), 7.39 (d, 2H, J=6.0 Hz), 8.38 (d, 2H, J=3.6 Hz).
