실험 절차

To a solution of [4-amino-2-(piperidin-4-ylamino)-pyrimidin-5-yl]-(2-methoxy-phenyl)-methanone trifluoroacetic acid salt (92.4 mg, Example 11) in methylene chloride (3 mL) were added triethylamine (0.12 mL, 0.861 mmol, Aldrich) and methyl isocyanate (6.2 mg, 0.107 mmol, Fluka) at 0° C. After stirring for 1 hour 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-(2-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidine-1-carboxylic acid methylamide (32.8 mg). HRMS, observed: 385.1985; Calcd for (M+H)+: 385.1983.
