Versuchsvorschrift
Hydrochloric acid (35 wt %, 1.47 ml) was added to 2,3-diamino-4-(2-thienyl)pyridine (1.46 g, 7.61 mmol) and orthoformic acid ethyl ester (40.5 ml). This solution was stirred at room temperature for 3 days and then filtered. The residue was washed with ether to give 7-(2-thienyl)-3H-imidazo[4,5-b]pyridine (1.74 g, 96%).
