実験手順

A mixture of 3-iodo-1-(3-methoxy-4-nitrophenyl)-1H-pyrazolo[4,3-d]pyrimidin-7-amine (300 mg, 0.728 mmol), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,6-tetrahydro-1-pyridinecarboxylate (270 mg, 0.874 mmol), sodium carbonate (185 mg, 1.75 mmol) and tetrakis(triphenylphosphine)palladium(0) (50 mg, 0.044 mmol) in 1,2-dimethoxy ethane (6 mL) and water (3 mL) was heated in an 85° C. oil bath for 1.75 hours. tert-Butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,6-tetrahydro-1-pyridinecarboxylate (45 mg, 0.146 mmol) was added to the mixture and then it was heated in the 85° C. oil bath for another 16 hours. The solvents were evaporated under reduced pressure then the residue was partitioned between water (10 mL) and ethyl acetate (15 mL). The layers were separated and then the aqueous layer was extracted with ethyl acetate (10 mL), dichloromethane (20 mL) and then a 10% solution of methanol in dichloromethane (20 mL). The organic solutions thus obtained were combined and evaporated to a residue which was purified by flash chromatography on silica gel using ethyl acetate as an eluent to provide the title compound as a yellow solid (205 mg, 60%): 1H NMR (DMSO-d6, 400 MHz) δ 8.40 (s, 1H), 8.10 (d, 1H), 7.50 (m, 1H), 7.42 (s, 1H), 7.31 (d, 1H), 7.1 (bs, 2H), 4.13 (m, 2H), 3.99 (s, 3H), 3.58 (m, 2H), 2.67 (m, 2H), 1.44 (s, 9H) RP-HPLC (Hypersil HS C18, 5 μm, 100 A, 250×4.6 mm; 5%-100% acetonitrile-0.05 M ammonium acetate over 25 min, 1 mL/min) tr 21.42 min; MS: M−H+ 466.3
