A mixture of 7g of 4-(N-p-toluenesulfonyl)amino-3-methyl-N-ethylaniline, 4g of β-methanesulfonamidoethyl chloride, 2.1g of sodium hydrogen carbonate, 16g of water and 30ml of methanol were refluxed for 5 hours, and then 16g of sulfuric acid were added thereto and the entire reaction system was again refluxed. Next, the reaction solution was condensed to half the original volume and 300ml of isopropyl alcohol were added thereto to separate crystals. The crystals were filtered out and dried to obtain 1.5g of 4-amino-3-methyl-N-(β-methanesulfonamidoethyl)-N-ethylaniline. sesquisulfate. H2O.
