Procedure

To 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 (0.12 mmol) and triethylamine (50 uL, 0.36 mmol) in DMF (1.5 mL) was added ethyl chloroformate (26 mg, 0.24 mmol). The mixture was stirred at room temperature for 2 hours. The reaction was filtered and the filtrate was purified by preparative RP-HPLC to give Ethyl 4-(4-(5-chloro-4-(5-methyl-1H-pyrazol-3-ylamino)pyrimidin-2-ylamino)-5-fluoro-2-methylphenyl)piperidine-1-carboxylate as a white solid: 1H NMR (400 MHz, MeOD-d4) δ 8.13 (s, 1H), 7.54 (d, 1H), 7.10 (d, 1H), 6.28 (s, 1H), 4.30-4.26 (m, 2H), 4.14 (q, 2H), 2.99-2.96 (m, 3H), 2.33 (s, 3H), 2.29 (s, 3H), 1.8-1.77 (m, 2H), 1.64-1.55 (m, 2H), 1.28 (t, 3H); ESMS m/z 488.2 (M+H+).
