To a solution of N-[5-(4,5-diphenyl-1H-imidazol-2-ylthio)pentyl]-1-heptanamine (1.0 g, 0.0024 mol) in hexane (50 mL) was added, dropwise, a solution of phenylisocyanate (0.27 mL, 0.298 g, 0.0025 mol) in hexane (25 mL) and the reaction mixture was stirred at ambient temperature for 4 hours. The reaction mixture was concentrated under vacuum and the residue was chromatographed with 6:4 hexane-ethyl acetate to give the title compound (0.5 g, 0.009 mol) as a yellow amorphous solid. 1H NMR (CDCl3) δ11.0(s,1H), 7.7-6.9(m,14H), 6.4(s,1H), 3.4(t,2H,J=7Hz), 3.2(t,2H,J=7Hz), 3.0(t,2H,J=7Hz), 1.9-1.1(m,16H), 0.9(t,3H,J=8Hz).
