Reaction Steps
To a solution of methyl 5-[(5-biphenyl-4-yl-6-chloro-1H-benzimidazol-2-yl)oxy]-2-methylbenzoate (11 g, 23.46 mmol) in MeOH/water (1:1) (250 mL) was added NaOH (5 M in water) (23.46 mL, 117 mmol). The mixture was heated at 70° C. for 1 h. The mixture was then cooled, diluted with water and acidified with 2 M aqueous HCl. The precipitated white solid was filtered and dried to afford the title compound as a white powder. LCMS: calculated for C27H19ClN2O3 454.90, observed m/e 455.5 (M+H)+ (Rt 2.27/4 min). 1H NMR (500 MHz, CD3OD): δ 7.98-7.35 (m, 14H), 2.62 (s, 3H).
