Reaction Steps

This material was prepared according to the method described in Example 66 using 4-[6-(4-trifluoromethyl-phenyl)-pyrimidin-4-yloxy]-benzooxazol-2-ylamine, (Example 70(c)), (0.27 g, 0.72 mmol) and acetic anhydride (82 uL, 0.87 mmol) in pyridine (3 mL). Purification by silica gel chromatography (1:1.5 of EtOAc/hexanes) provided the title compound as a white solid. MS (ESI, pos. ion) m/z: 415 (M+1). Mp: 205.1–205.2° C.
