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 (50.0 mg, 0.12 mmol), 1-(tert-butoxycarbonyl(methyl)amino)cyclobutanecarboxylic acid (27.5 0.12 mmol), HATU (45.8 mg, 0.12 mmol) and di-isopropylethylamine (20 μL, 0.12 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 concentrated in vacuo. The resulting crude mixture was dissolved in 5 mL of DCM and 4 mL of TFA, and was 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-(methylamino)cyclobutyl)methanone; ESMS m/z 527.2 (M+H+).
