Procedure
A mixture of 2-chloro-5-(3,5-dioxo-4,5-dihydro-3H-[1,2,4]triazin-2-yl)-benzoic acid (50 mg) in thionyl chloride (1 ml) was stirred at reflux for 1 hour. The mixture was concentrated under vacuum to provide 50 mg of the title intermediate as an amorphous amber solid that was used immediately in the next step.
Workup
- temperatureat reflux for 1 hour
