Reaktionsschritte

0.3 Gram of 2-nitro-5-(4-acetylamino-1-piperidyl)benzaldehyde dimethylacetal, 5 ml of formalin, 1 ml of ethanol and 2 drops of concentrated hydrochloric acid were refluxed by heating. After the reaction was completed, the solvent was removed by evaporation to obtain the residue, then water was added to the residue. The crystals formed were collected by filtration to yield 0.22 g of 2-nitro-5-(4-acetylamino-1-piperidyl)benzaldehyde.
