Reaction Steps

A solution of 5.0 g of 5-nitro-2-[2-(diethylamino)-ethyl]-2H-[1]benzopyrano[4,3,2-cd]indazol-8-ol in 200 ml of DMF with 0.2 g of 20% palladium hydroxide on carbon was stirred under a hydrogen atmosphere for 24 hours. The mixture was filtered and the filtrate was evaporated in vacuo to leave the product 5-amino-2-[2-(diethylamino)-ethyl]-2H-[1]benzopyrano[4,3,2-cd]indazol-8-ol as an oily solid.
