実験手順

To a solution of 3-(3-{3-[4-(4-biphenyl-2-ylmethyl-piperazin-1-yl)-benzyl]-2-imino-2,3-dihydro-benzoimidazol-1-yl}-propoxy)-benzoic acid ethyl ester (20 mg, 0.03 mmol) in MeOH (2 ml) at rt was added 1M NaOH (2 ml). The reaction was heated at to 80° C. for 5 h and then concentrated under reduced pressure. The material that remained was partitioned between EtOAc and H2O and the organic layer was separated, dried (Na2SO4), filtered and concentrated under reduced pressure to give 3-(3-{3-[4-(4-biphenyl-2-ylmethyl-piperazin-1-yl)-benzyl]-2-imino-2,3-dihydro-benzoimidazol-1-yl}-propoxy)-benzoic acid (10 mg, 52%). HPLC-MS [M+1]+ 327. 1H NMR (500 MHz, CHLOROFORM-d) □ ppm 2.13 (2 H, br s), 2.36 (4 H, br s), 2.87 (4 H, br. s.), 3.39 (2 H, s), 3.99 (2 H, br s), 4.39 (2 H, br s), 5.24-5.55 (2 H, m), 6.37-6.87 (3 H, m), 7.09 (7 H, br s), 7.29-7.67 (11 H, m).
