실험 절차

To a solution of 3-[3-(3-{4-[4-(4′-chloro-biphenyl-2-ylmethyl)-piperazin-1-yl]-benzyl}-2-imino-2,3-dihydro-benzoimidazol-1-yl)-propoxy]-benzoic acid ethyl ester (140 mg, 0.20 mmol) in THF (1.2 ml), MeOH (1.2 ml) and H2O (0.6 ml) at 0° C. was added LiOH.H2O (16 mg, 0.39 mmol). The reaction was warmed to rt where it was maintained for 20 h. After this time, the mixture was concentrated under reduced pressure and then partitioned between saturated NaHCO3 and dichloromethane to adjust the pH to ˜8. The organic phase was separated, dried (Na2SO4), filtered and concentrated under reduced pressure. Purification by preparative HPLC provided 3-[3-(3-{4-[4-(4′-chloro-biphenyl-2-ylmethyl)-piperazin-1-yl]-benzyl}-2-imino-2,3-dihydro-benzoimidazol-1-yl)-propoxy]-benzoic acid (15 mg, 11%). HPLC-MS 686 [M+1]+, 344.
