Participants

Reaction Steps

0.22 g (0.00068 mol) of 1,3-dimethoxy-5-(4-nitrophenylsulphonyl)-benzene was suspended in a mixture of 15 ml of methanol and 7.5 ml of water, treated with 0.30 g of iron powder and 0.30 g of NH4Cl and heated at reflux for 1 hr. After cooling the mixture was diluted with 50 ml of methanol, treated in an ultrasound bath for a short time and suction filtered. The filter material was washed with a large amount of methanol and the filtrate was concentrated. The residue was suspended in water and treated in an ultrasound bath. The precipitate which thereby resulted was filtered off under suction and dried in a high vacuum. There was obtained 0.18 g (90%) of 4-(3,5-dimethoxybenzenesulphonyl)-phenylamine as white crystals; m.p.: 128-130° C.
