Versuchsvorschrift
A mixture of 2,6-dibromo-[1,2,4]triazolo[1,5-a]pyridine (1 g, 3.61 mmol) and morpholine (10 g, 10 ml, 115 mmol) was refluxed for 4 hours under argon atmosphere. The mixture was evaporated to dryness under reduced pressure. Flash chromatography (silica gel, 50 g, 30-100% heptane/ethyl acetate) afforded 6-bromo-2-morpholin-4-yl-[1,2,4]triazolo[1,5-a]pyridine (672 mg, 66%) as a light yellow solid. Mp.: 136° C. MS: m/z=283.0/285.0 (M+H+).
