Reaction Steps
The title compound was prepared by treating 4-(2-benzyl-7-trifluoromethyl-2H-indazole-3-yl)-phenol (20 mg, 1 eq) with 2-(4-bromomethyl-phenyl)-propionic acid (39 mg, 3 eq) and potassium carbonate (37 mg, 5 eq) in DMF (2 mL) at 150° C. overnight. After cooling, water was added and the pH adjusted to 1 (aq. HCl, 2M) followed by extraction with dichloromethane. Purification by preparative HPLC gave the desired product in 45% yleld.
