How is Ethyl 6-bromo-1H-indazole-3-carboxylate (CAS: 885272-94-6) typically synthesized?

Ethyl 6-bromo-1H-indazole-3-carboxylate is synthesized through a multi-step process involving the synthesis of 1H-indazole followed by alkylation with ethyl bromide, followed by acylation with ethyl chloroformate. The reaction typically requires the use of a base like triethylamine and is achieved with high yield and selectivity. The process is conducted under standard laboratory conditions, with appropriate handling of bromine and ethyl bromide due to their reactivity.
