Procedure
(8-bromo-1-methyl-1,2,3,4-tetrahydrobenzo[e][1,4]diazepin-5-ylidenemethyl)phosphonic acid diethyl ester was prepared in an analogous fashion to (1-methyl-1,2,3,4-tetrahydrobenzo[e][1,4]diazepin-5-ylidenemethyl)phosphonic acid diethyl ester, prepared in Example 1, by replacing 2-fluorobenzoic acid with 2-fluoro-4-bromobenzoic acid.
