PROCEDURE

实验过程

To a solution of 5.0 g (13.7 mmol) of bis-tropan-3-yl succinate in 100 mL of dry acetone is added 9.8 g (34.3 mmol) of 3,4-diacetoxybenzyl bromide (prepared from 3,4-dihydroxybenzaldehyde through acetylation of the hydroxy groups, reduction of the aldehyde to the corresponding alcohol, and bromination). Then the mixture is heated at 60-70° C. for 10 hours. The precipitate is collected by filtration, washing with acetone and ether, and drying under vacuum to yield 9.6 g (75%) of bis-[N-(3,4-diacetoxybenzyl)tropanium-3-yl] succinate dibromide as a white powder, which is further purified by recrystallization with methanol-methylene chloride.
