On treatment with ammonia and benzaldehyde the benzalisoxazolone 3 does not give the aminoketone 7 as assumed by Speroni [1] but a product which has been shown to be identical with the enamine 8 prepared by Ried & Czack [4] from ethyl oximinoacetoacetate and benziminoethyl ether. Authentic aminoketone 7 was synthesized in a three-step procedure starting from the aminonitrile 19. Conversion of 7 into
