Reaction Steps
This material was prepared analogous to Example 146 by using N-{4-[5-bromo-4-(4-trifluoromethyl-phenyl)-pyridin-2-yloxy]-benzothiazol-2-yl}-acetamide, (Example 145(b)), (0.1 g, 0.2 mmol), 4-(trifluoromethoxy)phenyl boronic acid (53 mg, 0.26 mmol, Aldrich), Pd(PPh3)4 (23 mg, 0.02 mmol, Aldrich) and aq. Na2CO3 (32 mg in 0.4 mL of water) in dioxane (2 mL). Purification by silica gel chromatography (1:2 of EtOAc/hexanes), followed by preparative HPLC separation gave the title compound as a white solid. MS (ESI, pos. ion) m/z: 590 (M+1). Mp: 212.9–222.3° C.
