Procedure

To a solution of (3,5-dimethyl-pyridin-2-ylmethyl)-(3-isopropyl-pyridin-2-ylmethyl)-{2-[1-(toluene-4-sulfonyl)-1H-imidazol-4-yl]-ethyl}-amine (99.1 mg, 0.19 mmol) in anhydrous MeOH (1.5 mL) was added HOBT (108.5 mg, 0.803 mmol) and the resulting mixture was stirred overnight. The mixture was concentrated and purified by radial chromatography on silica gel (1 mm plate; using 6% MeOH/CH2Cl2, followed by CH2Cl2/MeOH/NH4OH; 17:1:1) to afford COMPOUND 176 as a light brown oil (43.4 mg, 62%). 1H NMR (CDCl3) δ 1.00 (d, 6H, J=9.0 Hz), 2.07 (s, 3H), 2.21 (s, 3H), 2.86 (s, 4H), 3.09 (qnt, 1H, J=6.0 Hz), 3.77 (s, 2H), 3.84 (s, 2H), 6.70 (s, 1H}, 7.11 (m, 2H), 7.43 (d, 1H, J=7.8 Hz), 7.57 (s, 1H), 8.14 (s, 1H), 8.32 (d, 1H, J=4.7 Hz). 13C NMR (CDCl3) δ 18.2, 18.3, 23.0, 23.5, 27.8, 54.8, 57.6, 58.2, 123.0, 124.4, 130.4, 132.0, 132.6, 133.6, 134.9, 139.1, 143.6, 145.8 146.3, 153.9, 155.7. ES-MS m/z 364 [M+H]+. Anal. Calcd. for C22H29N5.0.6H2O.0.1 CH2Cl2: C, 72.69; H, 8.04; N, 19.27. Found: C, 69.46; H, 8.11; N, 18.24.
