Reaction Steps

(Scheme 4 (T)) A solution of starting material 2-[5-(2-Methyl-4,5-diphenyl-imidazol-1-yl)-pentyl]-2-phenyl-malonic acid (580 mg, 1.32 mmole)) in glacial Acetic Acid (20 ml) was let stirred under reflux for 18 hrs. The next day, the reaction was let cooled to room temperature and concentrated in vacuo. Product was obtained (398.6 mg, 77.7%). 1H NMR (CDCl3): δ1.11 (b, 4H), 1.42 (bd, 2H), 1.59 (m, 1H), 1.96 (m, 1H), 2.55 (s, 3H), 3.43 (t, 1H), 3.96 (t, 2H), 7.199 (m, 3H), 7.27 (m, 7H), 7.39 (m, 2H), 7.45 (m, 3H), 11.857 (b, 1H), 13 C NMR (CDCl3): δ6 12.0, 21.4, 26.1, 26.8, 29.5, 29.7, 33.1, 44.2, 52.2, 127.0, 127.2, 127.4, 128.0, 128.4, 128.4, 128.5, 129.1, 129.3, 129.5, 130.6, 131.0, 133.0, 139.8, 144.1, 175.8, 177.7.
