Procedure

(1R,4S)-4-hydroxy-2,2-dimethyl-4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclohexanecarboxylic acid (100 mg, 0.197 mmol) was dissolved in methanol (3 ml) and concentrated sulfuric acid (10.52 μl, 0.197 mmol) added. The reaction mixture was stirred for 16 hours. The reaction mixture was diluted with water, extracted with ethyl acetate (3×) and washed with saturated aqueous sodium bicarbonate. Solvent evaporation gave the title compound (85 mg, 0.163 mmol, 83% yield).
