Reaction Steps

Part A. To a solution of 8-(4,5-diphenyl-1H-imidazol-2ylthio)octanoic acid (8.44 g, 0.02 mol) in methylene chloride (100 mL) at 0° was added, portionwise as a solid, dicyclohexylcarbodiimide (4.12 g, 0.02 mol), and the reaction mixture was stirred at 0° for 30 minutes. To this reaction mixture was added, dropwise, heptylamine (2.96 mL, 2.3 g, 0.02 mol) and the reaction mixture was stirred at reflux for 72 hours. The reaction mixture was cooled, and the solids were filtered and washed with chloroform. The filtrate was concentrated under vacuum and the residue was chromatographed with a gradient of 7:3 to 1:1 hexane-ethyl acetate. The resulting solid was recrystallized from acetonitrile and triturated with hexane to give 8-(4,5-diphenyl-1H-imidazol-2-ylthio) -N-heptyloctanamide (3.28 g, 0.0067 mol) as a white solid, mp 119°-120°. 1H NMR (DMSO-d6) δ 12.5(s,1H), 7.8-7.1(m,10H), 3.2-2.9(m,4H), 2.0(t,2H,J=7 Hz), 1.75-1.0(m,21H),1.0-0.8 (m,3H).
