Versuchsvorschrift

To a solution of 4-iodo-2-(6-methyl-pyridin-2-yl)-7H-pyrrolo[2,3-d]pyrimidine (Intermediate 3) (1 eq, 1.50 mmol, 530 mg) and 3-bromopyridine-5-boronic acid (ABCR GmbH & Co. KG, Karlsruhe, Germany) (1.1. eq, 1.65 mmol, 339 mg) in DME/EtOH (1:1, 6 ml) are added aqueous Na2CO3 solution (2 M, 3 eq, 4.50 mmol, 2.2 ml) and Pd(PPh3)4 (0.05 eq, 0.075 mmol, 89 mg). The resulting mixture is heated using microwave radiation at 120° C. for 20 min. After cooling down to r.t., the mixture is filtered and the resulting precipitate is washed with EtOH. The residue is suspended in DCM, filtered, and dried to give the title compound; [M+H]+=366/368; 1H-NMR (400 MHz, DMSO): δ 12.58 (s, 1H), 9.40 (m, 1H), 8.89 (m, 1H), H), 8.79 (m, 1H), 8.37 (t, 1H), 7.87-7.77 (m, 2H), 7.33 (t, 1H), 7.00 (m, 1H), 2.56 (m, 3H).
