Versuchsvorschrift

To a solution of N-{5-[(2-chloro-4-pyrimidinyl)ethynyl]-2-fluorophenyl}-2,2,2-trifluoroacetamide (4.6 g, 13 mmol) in DMF (100 mL) was added aminopyridinium iodide (5.9 g, 27 mmol) and K2CO3 (5.5 g, 40 mmol). After stirring 2 h at rt, the reaction mixture was diluted with diethyl ether (250 mL) and EtOAc (250 mL), and washed with water. The organic layer was adsorbed to silica gel and purified by column chromatography to afford the desired product (3.2 g, 55%) as a tan solid. 1H NMR (400 MHz, CDCl3): δ 8.57 (m, 2H), 8.31 (d, J=5.5 Hz, 1H), 8.14 (s, 1H), 7.47 (m, 2H), 7.31 (t, J=9.4 Hz, 1H), 7.04 (t, J=6.8 Hz), 6.99 (d, J=5.3 Hz, 1H). ES-LC/MS m/z=436 [M+H]+.

Aufarbeitung

  1. washwashed with water
  2. custompurified by column chromatography
