Procedure

A mixture of 5-chloro-N2-(2-fluoro-5-methyl-4-(piperidin-4-yl)phenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine (67.3 mg, 0.17 mmol), 1-(tert-butoxycarbonyl(ethyl)amino)cyclopropanecarboxylic acid (38.0 mg, 0.17 mmol), HATU (63.0 mg, 0.17 mmol) and diisopropylethylamine (57 μL, 0.34 mmol) in 1 mL of DMF was stirred at room temperature overnight. The reaction mixture was partitioned between EtOAc and water, the combined organic extracts were dried (Na2SO4) and then concentrated in vacuo. The resulting crude mixture was dissolved in 5 mL of DCM and 4 mL of TFA and was then stirred for 2 h followed by concentration in vacuo. The crude product was purified by RP-HPLC to afford (4-(4-(5-chloro-4-(5-methyl-1H-pyrazol-3-ylamino)pyrimidin-2-ylamino)-5-fluoro-2-methylphenyl)piperidin-1-yl)(1-(ethylamino)cyclopropyl)methanone; ESMS m/z 527.2 (M+H+).
