Reaction Conditions

Reaction Steps

A mixture of 11-cyano-9,10-dihydro-9,10-ethanoanthracene (4.6 g), ethylenediamine (1.5 g) and hydrogen sulfide (about 100 mg) is stirred at 130° C. for 20 hours. The reaction mixture is mixed with water and ether to be distributed in two layers. The ether layer is washed with water, dried, and evaporated to remove the ether. The residue is recrystallized from ether to give 11-(2-imidazolin-2-yl)-9,10-dihydro-9,10-ethanoanthracene (5.0 g) as crude crystals. IR (KBr), 1621 cm-1 (N--C=N).
