Abstract

Synthesis of Methyl 7,9-Dimethyl-5-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepine--1-carboxylate and Its Analogues. -The synthesis of (Ia) on an industrial scale is elaborated and applied to the preparation of (Ib,c) and (II). The adoption of the synthesis to analogues bearing methoxy, chloro, or fluoro instead of methyl substituents fails. -(VAID*, R. K.; BOINI, S. K.; ALT, C. A.; SPITLER, J. T.; HADDEN, C. E.; FRANK, S.
