Procedure

5-Hydroxy-5-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]azepan-2-one (Example 10, 300 mg, 0.65 mmol) was suspended neat in phosphorus pentoxide (1.2 mL, 12.9 mmol) and stirred at 65° C. for 2 h., then cooled to room temperature, and carefully poured into saturated aqueous sodium bicarbonate. After the exotherm ceased, the mixture was extracted with ethyl acetate (2×). The combined organic layers were dried over sodium sulfate, filtered, and concentrated. The residue was purified by reverse phase HPLC (45:55 to 85:15 acetonitrile:water with a 0.1% trifluoroacetic acid modifier) to afford 5-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]-1,3,6,7-tetrahydro-2H-azepin-2-one and 5-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]-1,3,4,7-tetrahydro-2H-azepin-2-one (70:30 mixture, 119 mg, 0.26 mmol, 41% yield) as a yellow solid. MS ESI: [M+H]+ m/z 446.1.
