HCID 601165Methyl 2-methyl-3-nitrobenzoate

Procedure

30 g (165.6 mmol) of 2-methyl-3-nitrobenzoic acid is added in 150 ml of methanol and after 2.9 ml of concentrated sulfuric acid is added, it is refluxed for two days. After cooling, the crystallizate (22.55 g=79%) is suctioned off and thus incorporated into the next stage.
