Reaction Steps
Potassium carbonate (5.19 mmol, 717 mg) in water (2.5 mL) and tetrakis(triphenylphosphine)palladium(0) (0.04 mol %, 80 mg) in ethyl alcohol (2.5 mL) were added to 2-amino-5-bromopyridine (1.73 mmol, 299 mg) and 1-naphthaleneboronic acid (2.60 mmol, 446 mg) in benzene (10.0 mL). After 2 hours at 90° C. the reaction mixture was quenched with water (30 mL) and extracted with dichloromethane (3×30 mL). The organic phases were concentrated in vacuo and the residue chromatographed on silica gel (eluted with 50% ethyl acetate in hexanes) to give 260 mg (Y: 68%) of the title compound 11a. MS (E+) m/z: 381 (MH+).
