HCID 601165Methyl 2-methyl-3-nitrobenzoate

Procedure

30 g (165.6 mmol) of 2-methyl-3-nitrobenzoic acid is added to 150 ml of methanol, and it is refluxed for two days after 2.9 ml of concentrated sulfuric acid is added. After cooling, the crystallizate (25.55 g=79%) is suctioned off and thus incorporated into the next stage.
