摘要：In order to establish the structure of 2'-(p-aminophenyl)-pyrimidinoisoquinoline derivative, a deaminated substance from a higher melting point was obtained from [2'-(p-aminophenyl)-4', 5'-dihydropyrimidino]-1', 6' : 1, 2-(3, 4-dihydro-6, 7-dimethoxyisoquinolinium chloride). The former was found to be identical with the product obtained by cyclization of N-(p-nitrobenzoyl-β-alanyl)-β-veratrylethylamine of higher melting point. Moreover, the hydrogenated prouct of pyrimidine moiety of pyrimidinoisoquinoline derivative was synthesized and successfully deaminated.
