Reaction Steps
As shown in Scheme 7, coupling of 3-bromo-4-nitrotoluene with 2-amino-benzoic acid via an Ullmann reaction yields an N-phenyl-anthranilic acid. After protection of the acid with 2-amino-2-methyl-1-propanol, oxidation affords the corresponding aldehyde. Addition of vinyl magnesium bromide and deprotection provides the N-phenyl-anthranilic acid containing a latent Michael acceptor. ##STR15## Figure legends
