Reaction Conditions:

with tetrakis(triphenylphosphine) palladium⁽⁰⁾;potassium carbonate in tetrahydrofuran;water at 80; for 2 h;

Steps:

2 synthesis of Intermediate B-1
2-bromo-naphthalene (2.07g, 10mmol), benzene-1,4-diBoronic acid(2.49g, 15mmol), Pd (PPh3) 4 (0.58 g, 0.5mmol), potassium carbonate (4.15g, 30mmol) and THF: H2O = 2:1 solution dissolved in 200ml 80 After 2 hours reflux agitation. Thereafter it was added and extracted three times with 40ml ethyl ether H2O40ml drying the obtained organic layer with magnesium sulfate, and separating the residue obtained by evaporating the solvent was subjected to silica gel column chromatography purification Intermediate B-1 (1.98g, 80% yield) It was obtained.
