A mixture of (R)-7-chloro-3-methyl-5-(tetrahydrofuran-3-ylamino)pyrido[4,3-d]pyrimidin-4(3H)-one (16 mg, 0.057 mmol), 1-methyl-4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperazine (19 mg, 0.063 mmol), Pd(PPh3)4 (6.6 mg, 0.0057 mmol), K2CO3 (24 mg, 0.17 mmol), 2-propanol (3 mL) and H2O (1 mL) was stirred at 90° C. overnight. The reaction mixture was cooled to room temperature and worked-up. The residue was purified using slilica gel flash column chromatography (eluent: 0-10% methanol in dichloromethane) to afford (R)-3-methyl-7-(4-(4-methylpiperazin-1-yl)phenyl)-5-(tetrahydrofuran-3-ylamino) pyrido[4,3-d]pyrimidin-4(3H)-one as a slightly yellow solid. HPLC-MS calculated C23H28N6O2(M+H+): 421.24, found: 421.20.
