Procedure
A mixture of 1,4-dichlorobenzo[g]phthalazine (9.23 mmol) and n-butylamine (20 mL) was heated in an autoclave at 130° C. for 12 h. After cooling to room temperature, the excess of n-butyl amine was evaporated to dryness under vacuum. When the residue was treated with acetone (100 mL) a yellow solid was formed. After being filtered off and dried it afforded 1.87 g (55% yield) of 1,4-bis(n-butylamino)benzo[g]phthalazine monohydrochloride. m.p. 195°-197° C.
