실험 절차

4-[4-Amino-5-(2,3-difluoro-6-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidine-1-sulfonic acid amide (50 mg, Example 285) in dichloromethane (10 mL), N-methyl morpholine (0.1 mL, Aldrich) and dimethylaminopyridine (1 mg, Aldrich) was chilled in ice and added acetic anhydride (5 drops). The mixture was stirred cold for two hours and quenched with methanol. The mixture was evaporated to dryness and chromatographed on silica gel (dichloromethane, then ethyl acetate). Fractions corresponding to product were combined and crystallized from dichloromethane/ethyl ether to give 45 mg of colorless material, MP 153° C. (dec). MS(ES) MH+485
