실험 절차
To a suspension of N-{4-[6-(2-amino-4-trifluoromethyl-phenyl)-pyrimidin-4-yloxy]-benzothiazol-2-yl}-acetamide, (Example 151), (0.20 g, 0.50 mmol) in toluene (10 mL) was added acetic anhydride (0.090 g, 0.80 mmol, Aldrich). The reaction mixture was heated at reflux for 3 h, allowed to cool to room temperature and concentrated in vacuum. The residue was dissolved in EtOAc (20 mL) and washed with satd NaHCO3 (2×20 mL), dried over Na2SO4, filtered and concentrated in vacuum. Purification by silica gel chromatography (1:1:0.5 CH2Cl2/hexanes/EtOAc) provided the title compound as an off-white solid. Mp: 259–261° C. MS (ESI, pos. ion) m/z: 488 (M+1).
