Several new bis-moxazines were prepared by the condensation of hydroquinone, formaldehyde, and representative primary amines in a molar ratio of 1: 4: 2. With benzylamine two isomeric products, 3, S-dibenzyl-2, 3, 4, 7, 8, 9-hexahydro-benzo [1, 2-e, 4, 5-e'] bis-m-oxazine (IC) and 2, 9-dibenzy1-1, 2, 3, 8, 9, 10-hexahydrobenzo [2, le, 3, 4-e'] bis- m-oxazine (IIa), were obtained. Analogous results were obtained with a- ...
