Acetic Acid → HCID 13343750, compound

Participants

Reaction Steps

39.6 g of 2-methyl-5-acetamino-6-nitro-1,3-benzodioxole were boiled at reflux for 1 hour in 4 l of methanol with 4 g of sodium methoxide. After adding 5 ml of glacial acetic acid, the solution was evaporated in vacuo. The last traces of glacial acetic acid were removed by evaporation with toluene. The residue was dissolved in methylene chloride and filtered through a small amount of silicon dioxide. The evaporated filtrate was crystallized from isopropanol. There were obtained 29.3 g (90.1% of theory) of 2-methyl-5-amino-6-nitro-1,3-benzodioxole of melting point 139° C.
