実験手順

To a solution of N4-((6-phenyl-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methyl)pyridine-3,4-diamine (0.0640 g, 0.202 mmol) in HOAc (5 mL) was added sodium nitrite (0.0153 g, 0.222 mmol) in water (2 mL). Stirred for 1 h. Concentrated. Took up in DMSO and purified on RPHPLC. Took fractions containing product and made basic with 91 sodium carbonate and removed volatiles in vacuo. Product crashed out and was isolated by filtration. MS m/z=329.2[M+1]+. Calc'd for C17H12N8: 328.3.
