Participants

Reaction Steps

trans-4-[5-(3-{[4-(Trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclohexane-carboxylic acid (27 mg, 0.060 mmol) was dissolved in DMF (0.60 mL). To this solution was added HATU (24.04 mg, 0.063 mmol), DIPEA (0.063 mL, 0.361 mmol), followed by cyclopropylamine (3.44 mg, 0.060 mmol). The reaction was complete after stirring 1 hour at room temperature. The reaction mixture was diluted with saturated NaHCO3 and 2-Me-THF. The phases were separated and aqueous was extracted twice with ethyl acetate. The combined organics were washed with brine, dried over sodium sulfate and were concentrated in vacuo. The residue was purified by column chromatography on silica gel (Combiflash, 0-50% EtOH in DCM) to yield trans-N-cyclopropyl-4-[5-(3-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclohexanecarboxamide (10.9 mg, 0.022 mmol, 37.1% yield) as an off-white solid.
