Procedure

A solution of N-{5-[(5-amino-2-methylphenyl)amino][1,3]thiazolo[5,4-d]pyrimidin-2-yl}acetamide (120 mg, 382 μmol) produced in Example D35(v), 3-(1,1-dimethylprop-2-yn-1-yl)benzoic acid (458 mg, 458 μmol) produced in Example D20(iii) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (174 mg, 458 μmol) in pyridine (4 mL) was stirred at room temperature for 1 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, 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 (hexane/ethyl acetate=20/80→0/100), and the fractions containing the object product were concentrated under reduced pressure. The obtained residue was recrystallized from tetrahydrofuran to give the title compound (145 mg, 78%) as colorless crystals.
