Hydrochloric Acid → 1-[5-(3-Methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclohexanecarboxamide

A mixture of 1-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclohexanecarbonitrile (45 mg, 0.10 mmol) and NaOH (1M in MeOH, 0.5 ml, 0.50 mmol) was heated at 100° C. in the microwave for 16 hrs. The mixture was brought to pH=3 by addition of HCl (1.0 N in H2O) and then partitioned between EtOAc (5 mL) and brine (5 mL). The organic layer was separated, dried (Na2SO4), filtered and the volatiles were removed under reduced pressure. The residue was purified by HPLC (gradient elution 40% to 100% CH3CN in H2O/0.1% TFA, 20 mins, 20 ml/min) to give the title compound (4.0 mg, 8.67 μmol, 8.5% yield) as a white solid.
