Versuchsvorschrift

To a 250 mL round flask was added 2-chloro-3-phenylthio-4-aminopyridine (2.7 g, 11.4 mmol), and 60 mL of glacial AcOH. To this clear solution, ButONO (1.36 g, 11.45 mmol) was added drop by drop. After stirring at room temperature for 1 h, another (1.36 g 11.45) mmol of ButONO was added. The mixture was continued to stir at room temperature for 18 h. The reaction was quenched by water, and the product was purified by a silica gel column. Yield (88%) of 1-chloro-benzothieno[2,3-c]pyridine was 2.2 g.
