Participants

Reaction Steps

(a-2) A mixture of 53.7 parts of 2-nitro-N-propyl-4-[(propylimino)methyl]benzenamine, 360 parts of concentrated hydrochloric acid and 300 parts of water was stirred and refluxed for 30 minutes. The reaction mixture was cooled and the product was extracted with trichloromethane. The extract was dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using trichloromethane as eluent. The pure fractions were collected and the eluent was evaporated, yielding 20.4 parts of 3-nitro-4-(propylamino)benzaldehyde; mp. 73.6° C. (int. 2)
