Nine kinds of quaternary salts of phthalazines, possessing a substituent (C_6H_5,C_6H_5-CH_2,CH_3,RO) in 1-position, were synthesized, and it was clarified that the nitrogen in 3-position had been quaternized in these compounds. Since the methiodide of 1-methyl-4-ethoxyphthalazine formed a trimethinecyanine dye, the quaternization had taken place at the nitrogen in 2-position in this case. Structure of main products was determined when these quaternary salts were (a) heated above their decomposition temperature and (b) when they were reacted with silver oxide in the cold.
