실험 절차

The starting material is prepared as follows: The mixture of 3,078 g of o-nitrobenzylamine and 2,670 g of 2,5-dimethoxytetrahydrofuran is added rapidly to 10,000 ml of glacial acetic acid at 86° while stirring under nitrogen. The mixture is stirred at 95° for 1.25 hours, cooled to 25° and combined with 30,000 ml of water. It is extracted with ethyl acetate, the extract is washed with 10% aqueous sodium hydroxide and 10% aqueous sodium chloride, filtered and evaporated to yield the 1-(o-nitrobenzyl)-pyrrole.
