Reaction Steps

1-[5-(3-Methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclopropanecarboxylic acid (TFA salt, 110 mg, 0.206 mmol), formic acid hydrazide (37 mg, 0.617 mmol), HOBT (95 mg, 0.617 mmol), and EDC (118 mg, 0.617 mmol) were combined with DMF (5 mL) and DIEA (80 mg, 0.617 mmol). The reaction was stirred for 3 h at room temperature. It was subsequently diluted with water and extracted with ethyl acetate (2×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated. The residue was triturated with ether and filtered to provide N′-formyl-1-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclopropanecarbohydrazide (88 mg, 92%) as a colorless solid. MS ESI: [M+H]+ m/z 463.0.
