Procedure
To a solution of (3,5-dimethyl-pyridin-2-ylmethyl)-{3-[1-(4-fluoro-phenyl)-1-methyl-ethyl]-pyridin-2-ylmethyl}-{2-[1-{toluene-4-sulfonyl)-1H-imidazol-4-yl]-ethyl}-amine (87.3 mg, 0.143 mmol) in anhydrous MeOH (1.5 mL) was added HOBT (77.1 mg, 0.57 mmol). After stirring overnight the reaction mixture was concentrated. Purification by radial chromatography on silica gel using 5% MeOH/CH2Cl2 afforded COMPOUND 175 (36 mg, 55%) as a clear oil. 1H NMR (CDCl3) δ 1.65 (s, 6H), 1.97 (s, 3H), 2.20 (s, 3H), 2.53 (s, 4H), 3.30 (s, 2H), 3.37 (s, 2H), 6.63 (s, 1H), 6.88 (t, 2H, J=8.52 Hz), 7.04 (m, 3H), 7.30 (m, 1H), 7.61 (s, 1H), 7.93 (d, 1H, J=7.91 Hz), 8.05 (s, 1H), 8.55 (d, 1H, J=3.58 Hz). 13C NMR (CDCl3) δ 18.1, 18.2, 22.8, 31.4, 42.4, 53.3, 57.8, 58.8, 115.5, 115.8, 122.4, 124.1, 127.5, 127.6, 130.2, 132.1, 132.6, 134.5, 134.7, 139.2, 144.0, 145.4, 146.4, 146.5, 153.4, 158.5, 159.8.
