Versuchsvorschrift

To NMP (41.3 mL) and 4-methoxybenzylamine (3.66 mL, 28.1 mmol) was added K2CO3 (7.76 g, 56.2 mmol) and 4-chloro-2-iodo-thieno[3,2-c]pyridine-7-carbonitrile 26 (7.52 g, 23.4 mmol). The reaction was heated to 80° C. After 1.5 h, NMP was distilled away under reduced pressure. The resulting solids were suspended in H2O (500 mL) and filtered. The product was recrystallized from 350 mL of toluene to obtain 7.75 g of 27. 1H NMR (400 MHz, d6-DMSO) δ 8.58 (t, J=6 Hz, 1H), 8.35 (s, 1H), 8.17 (s, 1H), 7.28 (d, J=9 Hz, 2H), 6.89 (d, J=9 Hz, 2H), 4.68 (d, J=6 Hz, 2H), 3.37 (s, 3H).
