反応手順

Potassium carbonate (5 g) followed by 1-(chloromethyl)naphthalene (4.60 g) were added to a solution of diethyl 3,4-pyrroledicarboxylate (5.00 g) in acetone (50 ml). The mixture was stirred at room temperature for 4 days, dilute hydrochloric acid (100 ml) was added and the mixture was extracted with ether (2×100 ml). The organic extracts were dried, filtered and evaporated to give the sub-title compound as a solid (7.62 g).
