Di(succinimido) carbonate → methyl 4-({[(2,5-dioxo-1-pyrrolidinyl)oxy]carbonyl}amino)-1H-indazole-1-carboxylate

Participants

Reaction Steps

Methyl 4-amino-1H-indazole-1-carboxylate (1.9 g, 10 mmol) and 1-({[(2,5-dioxo-1-pyrrolidinyl)oxy]carbonyl}oxy)-2,5-pyrrolidinedione (2.8 g, 11 mmol) were combined in acetonitrile (100 mL), stirred for 48 hours at ambient temperature, and filtered. The filter cake was washed with acetonitrile (10 mL) and dried under reduced pressure at ambient temperature to provide the title compound.
