実験手順

To a solution of [4-amino-2-(piperidin-4-ylamino)-pyrimidin-5-yl]-(2-methoxy-phenyl)-methanone trifluoroacetic acid salt, (31 mg, Example 11) in dimethylformamide (2 mL) were added triethylamine (19 mg, 0.193 mmol, Aldrich), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (6.6 mg, 0.0344 mmol, Aldrich), 1-hydroxybenzotriazole hydrate (5.0 mg, 0.037 mmol, Aldrich), followed by acetic acid (2.3 mg, 0.034 mmol). The reaction mixture was stirred overnight at room temperature, taken up in ethyl acetate (15 mL), washed with brine and evaporated. The crude product was purified on silica gel with 95:5 of dichloromethane/methanol to give 1-[4-[4-amino-5-(2-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidin-1-yl]-ethanone (11.2 mg). HRMS, observed: 370.1875; Calcd for (M+H)+: 370.1874.
