Title: Ring contraction of 1,3-bis(5-bromopentyl)alloxazine.
Authors: Semenov, V. E.; Giniyatullin, R. Kh.; Sharafutdinova, D. R.; Reznik, V. S.
Abstract: The reaction of 1,3-bis(5-bromopentyl)alloxazine with ethylamine in propan-2-ol resulted in replacement of the terminal bromine atoms by ethylamino groups and was accompanied by contraction of the pyrimidine ring so that the products were 1,3-bis[5-(ethylamino)pentyl]alloxazine and 1,3-bis[5-(ethylamino)-pentyl]imidazo[4,5- b]quinoxalin-2-one.
