Synthesis of 4.5-dichloro-2-((3-chloropyridin-2-vnmethvnpyridazin-3(2HV one (G3-2 32 G3-2 To a solution of compound 4 (200 mg, 1.21 mmol), compound 32 (235 mg, 1.45 mmol) and K2CQ3 (335 mg, 2.42 mmol) in DMF (3 mL) was added KI (20 mg, 0.12 mmol). The solution was stirred at 90 C for 2h. The mixture was cooled to room temperature and quenched with water, extracted with EtOAc for 3 times, combined the organic layer, washed with brine, dried over Na2S(X filtered, concentrated under reduced pressure, purified by HPLC to give G3-2 (126 mg, 42%) as a yellow solid. NMR (DMSO-ifc, 300 MHz): delta 5.53 (s, 2H), 7.38-7.42 (m, 1H), 7.99 (d, J = 8.1 Hz, 1H), 8.27 (s, 1H), 8.41 (d, J = 4.5 Hz, 1H); LCMS [mobile phase: 20-95% Acetonitrile +0.02% NHtOAc] purity is >95%, Rt = 3.365 min; MS Calcd.: 290; MS Found: 291 (M+l)+.
The synthetic route of 185315-53-1 has been constantly updated, and we look forward to future research findings.
