実験手順

To a solution of N-[5-(4,5-diphenyl-1H-imidazol-2-ylthio)pentyl]-1-heptanamine (0.75 g, 0.0017 mol), prepared according to the procedure of Example 1, Part D, in hexane (40 mL) was added, dropwise, a solution of 2,4-dimethoxyphenylisocyanate (0.358 g, 0.002 mol) in hexane (20 mL) and the reaction mixture was stirred at ambient temperature for 4.5 hours. The reaction mixture was concentrated under vacuum and the residue was chromatographed with 7:3 hexane-ethyl acetate. The resulting solid was triturated with hexane to give the title compound (0.83 g, 0.0014 mol) as a glassy solid. 1H NMR (CDCl3) δ7.7-7.1(m,10H), 6.8-6.1(m,3H), 3.8(s,3H), 3.7(s,3H), 3.45(s,1H), 3.4-3.3(m,2H), 3.2(t,2H,J=7Hz), 3.0(t,2H,J=7Hz), 1.8-1.1(m,16H), 0.9(t,3H,J=8Hz).
