Procedure

To a solution of 4-[6-(4-trifluoromethyl-phenyl)-pyrimidin-4-yloxy]-benzothiazol-2-ylamine, (Example 65), (0.19 g, 0.5 mmol) in DMF (1.5 mL) was added methanesulfonyl chloride (92 uL, 1.2 mmol) and triethylamine (0.2 mL, 1.5 mmol). The reaction mixture was stirred at 60° C. for 1 h, at 110° C. for 16 h, allowed to cool to room temperature and partitioned between EtOAc and brine. The layers were separated and the aqueous layer was extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated under vacuum. Purification of the residue by silica gel chromatography (1:1 of EtOAc/hexanes) provided the title compound as an off-white solid. MS (ESI, pos. ion) m/z: 467 (M+1).
