Reaction Conditions:

with tetrakis(triphenylphosphine) palladium⁽⁰⁾;potassium carbonate in tetrahydrofuran;water at 60; for 3 h;

Steps:

1-1

2,3-dichloroquinoxaline30 g (150.7 mmol) of phenylboronic acid solution,150.7 mmol, tetrahydrofuran 450 mL,Mix 150 mL of water and heat to 60 ° C. Potassium carbonate452.1 mmol, tetrakis triphenylphosphine palladiumAnd the mixture was stirred for 3 hours under reflux.After the reaction,The reaction solution returned to room temperature was extracted, ethanol was added to the organic layer, The precipitate was washed sequentially with pure water and ethanol.This solid was recrystallized twice with toluene / hexane,32.6 g of Compound 1-A was obtained (yield: 90%).
