실험 절차

23.6g (0.1 mole) of 4-acetamino-3-methyl-N-(β-hydroxyethyl)-N-ethylaniline were dissolved in 30g of 50% sulfuric acid. The system was reacted for 5 hours at 80° to 100° C while stirring, and then put into 300 ml of isopropyl alcohol and stirred therein while cooling. Crystals separated out, which were then filtered and dried to obtain 22.2g of 4-amino-3-methyl-N-(β-hydroxyethyl)-N-ethylaniline sulfate.
