実験手順

8-Ethyl-2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-7-oxo-7,8-dihydro-pyrido[2,3-d]pyrimidine-6-boronic acid (21, 71 mg, 0.17 mmol), 5-bromo-2,2′-bithiophene (47 mg, 0.19 mmol), sodium carbonate (55 mg, 0.52 mmol) and Pd(PPh3)4 (20 mg, 0.02 mmol) were mixed under argon in a degassed mixture of dimethoxyethane:water (10:1, 3 mL). The resulting suspension was irradiated for 60 min at 120° C. in a microwave reactor. After completion, the reaction mixture was evaporated and the residue was purified by column chromatography using dichloromethane:methanol (100:5) as eluent. The crude product was triturated with ethyl acetate (10 mL) and collected by filtration. The title compound (30 mg, 0.057 mmol, 33%) was obtained as a yellow solid.
