Dichloromethane → 2-Tert-butylpyrene

Participants

Reaction Steps

A mixed solution of 150 g of pyrene, 75.52 g of t-butyl chloride and 742 ml of dichloromethane was cooled to 0° C. under a nitrogen stream, and 98.9 g of aluminum chloride was added. After this mixed solution was stirred at room temperature for 3 hours, 1100 ml of water was added, and this was extracted with 1100 ml of dichloromethane. The organic layer was washed with 750 ml of water three times, dried with magnesium sulfate, and evaporated, and this was purified by methanol washing, and filtered. After the resultant was vacuum dried, 272 g (content 79.2%) of 2-t-butylpyrene was obtained.
