Participants

Reaction Steps

3-amino-6-(4-((2-methoxyethoxy)methoxy)-3-(trifluoromethyl)phenyl)-4-(methylamino)picolinonitrile (100 mg) was suspended in dioxane (1500 μl) and water (1500 μl) and cooled to 0° C. Hydrochloric acid (2M, 189 μl) followed by dropwise addition of sodium nitrite (25 mg) in water (500 μl) and the mixture stirred at room temperature for 2 hours. The suspension was filtered and the solid washed with water to afford pale brown solid 6-(4-((2-methoxyethoxy)methoxy)-3-(trifluoromethyl)-phenyl)-1-methyl-1H-[1,2,3]triazolo[4,5-c]pyridine-4-carbonitrile (92% yield).
