Procedure
A mixture of 2-thiophenecarboxylic acid (15 mg, 0.12 mmol), DIPEA (129 mg, 1.00 mmol) and O-(7-azabenzotriazol-1-yl)N,N,N′,N′-tetramethyluronium hexafluorophosphate (44 mg, 0.12 mmol) in DMF (5 mL) was stirred at room temperature for 30 minutes. N4-(3-methoxyphenyl)-N6,N6-dimethyl-2-(1-piperazinyl)-4,6-pyrimidinediamine (36 mg, 0.10 mmol) was added to the above mixture and stirred at room temperature for 16 h. The crude product was treated with saturated NaHCO3 (50 mL) and extracted with EtOAC (3×50 mL). The organic layer was washed with brine (2×100 mL), dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by chromatography on silica using hexane/EtOAc (1:3), giving the desired product (25 mg, 57%).
