Reaction Steps

To a solution of 17.55 g of cis/trans-1,3-diaminoindan in 102 mL of pyridine was slowly added 102 mL of acetic anhydride. After 17 hrs the reaction mixture was added to 250 mL of water and 300 mL of methylene chloride. The insoluble precipitate was isolated from this three-phase mixture by filtration and dried to give 8.7 g of crude title compound which was recrystallized from ethanol to give 5.4 g pure material.
