Versuchsvorschrift

To a solution of 6-trifluoromethylsulfonyloxy-8-(3-nitrophenyl)-1,7-naphthyridine (300 mg, 0.75 mmol; prepared according to example 8) in tetrahydrofuran (5 ml) is added phenylboronic acid (118 mg, 0.97 mmol, bis(dibenzylideneacetone) palladium (18 mg, 0.03 mmol), triphenylphosphine (16 mg, 0.06 mmol) and aqueous Na2CO3 (2N, 1.44 ml). The solution is kept at 60° C. for 20 h. The solution is diluted with ethyl acetate, filtered and washed with 1N NaOH and water. The solvent is removed in vacuo to give pure product. Mass M+H 328. mp 172-175° C.
