Reaktionsschritte
In a typical run, 790 mg of 2-amino-3-hydroxypyridine (7.24 mmol) and 1.00 g of 5-aminonicotinic acid (7.24 mmol) were mixed with 10 mL of PPA and stirred at 200° C. for 6 hours. The reaction mixture was cooled to about 100° C. and carefully poured into 100 mL of water. The pH was brought to 6 with solid NaOH and the solids were collected by filtration. After drying under high vacuum, a total of 180 mg of 5-oxazolo [4,5-b]pyridin-2-yl-pyridin-3-ylamine.
