Versuchsvorschrift

A solution of N-{5-[(3-aminophenyl)(cyclopropyl)amino][1,3]thiazolo[5,4-d]pyrimidin-2-yl}acetamide (120 mg, 353 μmol) produced in Example D21(v), 3-(trifluoromethoxy)benzoic acid (77 mg, 371 μmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (161 mg, 424 μmol) in pyridine (3 mL) was stirred at room temperature for 30 min. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution (15 mL), and the mixture was extracted with ethyl acetate (20 mL, 5 mL). The combined organic layer was washed with saturated brine (5 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (ethyl acetate/methanol=100/0→98/2), and the fractions containing the object product were concentrated under reduced pressure. The obtained residue was recrystallized from ethyl acetate to give the title compound (134 mg, 71%) as colorless crystals.
