Reaction Conditions

Reaction Steps

To a mixture of N-{4-[6-(2-hydroxy-4-trifluoromethyl-phenyl)-pyrimidin-4-yloxy]-benzothiazol-2-yl}-acetamide, (Example 137), (0.20 g, 0.50 mmol) and potassium carbonate (0.062 g, 0.45 mmol, Aldrich) in anhydrous acetone (2 mL) was added benzyl bromide (0.053 mL, 0.45 mmol, Aldrich) and the reaction mixture was heated at 70° C. for 2 h. The solvent was removed under vacuum and the residue was diluted with water (50 mL) and extracted with ether (2×100 mL). The combined organic extracts were washed with water (100 mL), dried over Na2SO4, filtered and concentrated under vacuum. The crude material was purified by silica gel chromatography (gradient: 5-60% EtOAc/hexanes) to obtain the title compound (0.030 g, 13%) as a white solid. Mp: 201-203° C. MS (ESI, pos. ion.) m/z: 537 (M+1).
