Reaction Steps

3-[4-Amino-5-(2-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidine-1-carboxylic acid tert-butyl ester (76 mg, Example 52) was dissolved in dichloromethane (4 mL), cooled to 0° C. and treated with trifluoroacetic acid (1 mL). After stirred 30 minutes at 0° C., the reaction mixture was concentrated in vacuo to give [4-amino-2-(piperidin-3-ylamino)-pyrimidin-5-yl]-(2-methoxy-phenyl)-methanone as a trifluoroacetic acid salt. A portion of this material was partitioned between ethyl acetate and aqueous sodium carbonate to give the free base. (129.5 mg). MS (M+H)+, 328.
