Versuchsvorschrift

To a solution of N-{3-[(2-amino[1,3]thiazolo[5,4-d]pyrimidin-5-yl)(methyl)amino]phenyl}-3-(1-cyano-1-methylethyl)benzamide (150 mg, 338 μmol) produced in Example D5(i) in pyridine (4 mL) were added 2-methyl-1H-imidazole-5-carboxylic acid (146 mg, 1.01 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (770 mg, 2.03 mmol), and the mixture was stirred at 90° C. for 20 hr. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution (15 mL), and the mixture was extracted with ethyl acetate (20 mL, 10 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→90/10), and the fractions containing the object product were concentrated under reduced pressure. The obtained residue was recrystallized from tetrahydrofuran and methanol to give the title compound (122 mg, 65%) as colorless crystals.
