Hydrochloric Acid → 6-Amino-5-chloro-2-methyl-1-indanone

Participants

Reaction Steps

13.6 Milliliters of concentrated hydrochloric acid are added dropwise to a mixture of 30.7 g (0.136 mole) of 5-chloro-2-methyl-6-nitro-1-indanone and 24.55 g of iron powder in 340 ml of ethanol, and the suspension is boiled for 4 hours. The mixture is filtered off with suction from the precipitate in a hot state, after which process the compound precipitates partially from the filtrate when cooling. After having distilled off the solvent to a large extent, the precipitate is completed by diluting with water.
