HCID 14744905HCID 14744905, compound

Procedure

100 g (0.31 mol) of 2-(2'-dimethylaminoethenyl)-1-nitroanthraquinone are refluxed with 200 g of concentrated hydrochloric acid (38% strength) and 600 g of water for 2 hours. After cooling, the precipitated crystals are filtered off, washed with water until neutral and dried at 70° C. This leaves 90.5 g (98.7%) of 1-nitro-2-(2'-oxoethyl)anthraquinone; melting point: 192° C.
