Reaction Steps

To a solution of [4-amino-2-(piperidin-4-ylamino)-pyrimidin-5-yl]-(5-fluoro-2-methoxy-phenyl)-methanone as a trifluoroacetic acid salt (57.1 mg, Example 59) in dichloromethane (2 mL) were added triethylamine (58 mg, 8 equiv, Aldrich) and methyl chloroformate (6.7 mg, 1 equiv, Aldrich) at 0° C. After stirring for -2 hours at 0° C., the reaction mixture was concentrated in vacuo and crude product was purified on silica gel with 95:5 of dichloromethane/methanol to give 4-[4-amino-5-(5-fluoro-2-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidine-1-carboxylic acid methyl ester (23.7 mg). MS (M+H)+, 404.
