4-chloro-1-morpholin-4-ylbutan-1-one

Conditions: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

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 (41 mg, 0.1 mmol), 4-chloro-1-morpholinobutan-1-one (29 mg, 0.15 mmol) and DIEA (0.1 mL, 0.58 mmol) in NMP (1 mL) was stirred at 80° C. After 10 h, additional 4-chloro-1-morpholinobutan-1-one (51 mg) was added, and the reaction continued overnight. The crude product was purified by RP-HPLC to give 4-(4-(4-(5-Chloro-4-(5-methyl-1H-pyrazol-3-ylamino)pyrimidin-2-ylamino)-5-fluoro-2-methylphenyl)piperidin-1-yl)-1-morpholinobutan-1-one as a white powder; ESMS m/z 571.3.3 (M+H+). the reaction continued overnight The crude product was purified by RP-HPLC
