실험 절차

Terephthaloyl dichloride (5.0 g: 24.6 mmol) was dissolved in 50 ml of dehydrated pyridine, and tert-butanol (4.0 g: 54.1 mmol) was added to the mixture. The reaction was carried out at a room temperature for 24 hours. The reaction mixture was poured into an iced water, and the resultant mixture was acidified by adding hydrochloric acid. The resultant precipitate was collected by filtration, washed with water, dried, and recrystallized from methanol to provide 6.1 g (21.9 mmol) of 1,4-di(tert-butyl) terephthalate.
