Procedure
To a mixture of N-{4-[5-bromo-4-(4-trifluoromethyl-phenyl)-pyridin-2-yloxy]-benzothiazol-2-yl}-acetamide, (Example 145(b)), (51 mg, 0.1 mmol) and 4-fluorophenylboronic acid (18 mg, 0.13 mmol, Aldrich) in dioxane (1 mL) was added Pd(PPh3)4 (6 mg, 0.005 mmol, Aldrich) and aqueous Na2CO3 (16 mg in 0.2 mL of water). The reaction mixture was heated in microwave synthesizer at 160° C. for 30 min. Purification by silica gel chromatography (EtOAc/hexanes) gave the title compound as a white solid. MS (ESI, pos. ion) m/z: 524 (M+1). Mp: 112.3–130.1° C.
