Reaction Steps

To 3.5 g (25 mmol) of pyrazinoyl chloride dissolved in methylene chloride (20 mL) and pyridine (2 mL) cooled to 0° C. in a 50 mL round bottom flask was added 4-phenyl-phenol (5.0 g, 30 mmol). Upon completion of the reaction and isolation as described above recrystallization from hexanes yielded 3.15 g (39% yield) of the crystalline title compound; m.p: 95°-98° C. Elemental Analysis: C17H12N2O2Calcd: C:73.90, H:4.38. Found: C:73.68, H:4.28.
