A solution of N1-(3,5-Dimethyl-pyridin-2-ylmethyl)-N1-{3-isopropyl-pyridin-2-ylmethyl}-butane-1,4-diamine (110 mg, 0.328 mmol) and sulfamide (94 mg, 0.98 mmol) in 1,4-dioxane (6 mL) was refluxed for 25 hours then cooled to room temperature and concentrated. Purification of the crude material by radial chromatography on silica gel (1 mm plate, 50:1:1 CH2Cl2-MeOH—NH4OH) provided 51 mg (35%) of COMPOUND 152 as a white foam. 1H NMR (CDCl3) δ 1.03 (d, 6H, J=6.6 Hz), 1.42-1.50 (m, 2H), 1.59-1.66 (m, 2H), 2.15 (s, 3H), 2.28 (s, 3H), 2.58 (t, 2H, J=6.6 Hz), 2.93-3.03 (m, 3H), 3.70 (s, 2H), 3.73 (s, 2H), 5.15 (br s, 2H), 6.04 (br s, 1H), 7.16 (dd, 1H, J=7.8, 4.8 Hz), 7.25 (s, 1H), 7.54 (dd, 1H, J=7.8, 1.0 Hz), 8.25 (s, 1H), 8.41 (dd, 1H, J=4.8, 1.0 Hz); 13C NMR (CDCl3) δ 18.29, 18.37, 21.98, 23.60 (2 carbons), 27.53, 27.73, 42.81, 53.61, 57.69, 58.48, 123.28, 132.37, 133.15, 133.93, 139.23, 144.17, 146.13, 146.64, 154.10, 155.82; ES-MS m/z 420 (M+H). Anal. Calcd. For C21H33N5O2S.0.3CH2Cl2.0.5H2O: C, 56.34; H, 7.68; N, 15.42; S, 7.06. Found: C, 56.69; H, 7.45; N, 15.05; S, 6.76.
