Reaction Steps

A mixture of 5-bromo-8-(2,5-dimethyl-pyridin-3-yl)-quinoxaline (Step 99.4) (189 mg, 0.60 mmol) and CuCN (70 mg, 0.78 mmol, 1.3 equiv) in NMP (2 mL) was stirred for 6 h at 160° C., under an argon atmosphere. The reaction mixture was allowed to cool to rt, diluted with DCM/10% aqueous solution of ethylenediamine (25 mL), extracted with DCM. The organic phase was washed with H2O and brine, dried (Na2SO4), filtered and concentrated. The residue was purified by silica gel column chromatography (DCM/MeOH/NH3aq, 94:5:1) to afford 150 mg of the title compound as a yellow solid. Title compound: ESI-MS: 261.2 [M+H]+; tR=1.92 min (System 1); TLC: Rf=0.68 (DCM/MeOH/NH3aq, 94:5:1).
