Here is a downstream synthesis route of the compound, Product Details of 105166-53-8, blongs to pyridine-derivatives compound. Product Details of 105166-53-8

General procedure: Trifluoroacetic acid (0.75 mL, 0.009 mol) was added to a cooled (0 C) solution (4.5 mL CH2Cl2) of3-amino-2,2?-bipyridine (0.513 g, 0.003 mol), followed by isoamyl nitrite (0.61 mL, 0.004 mol). After 1 h,the diazonium salt of 3-amino-2,2?-bipyridine was precipitated out by cooling the reaction mixtureto -78 C, followed by the addition of diethyl ether (30 mL). The precipitate was filtered. A sample(2 mmol; 0.27 g) of indol-2-one was dissolved in dilute potassium hydroxide solution (15 mL) andcooled in a saltice bath and then cold diazonium solution was added to this cooled solution portionwise by stirring. The solution was further stirred at 0-5 C for 1 h. The pH of the reaction mixturewas maintained at 4-6 by the addition of solid sodium acetate in portions. The mixture was stirredfor 24 h at room temperature. The resulting solid was filtered, washed with cold water, and air-dried.Crystallization from ethanol gave yellow crystalline.
