Reaction Steps

A solution of 4-(4-(5-chloro-4-(5-methyl-1H-pyrazol-3-ylamino)pyrimidin-2-ylamino)-2,5-dimethylphenyl)-1-(4-methoxybenzyl)piperidin-2-one (45 mg) in TFA (0.5 mL) was heated to 100° C. for 24 hr. After cooling down to room temperature, the mixture was concentrated and purified by preparative RP-HPLC to provide 4-(4-(5-chloro-4-(5-methyl-1H-pyrazol-3-ylamino)pyrimidin-2-ylamino)-2,5-dimethylphenyl)piperidin-2-one. ESMS m/z 426.2 (M+H+).
