The methyl ester 8a, prepared from commercially available 3,4-diaminobenzoic acid, has been reacted with N,N -di(fert-butoxycarbonyl)thiourea in the presence of mercury chloride to provide the C3 guanylated intermediate 8b. The selectivity observed in this reaction arises from the decreased nucleophilicity of the C4 amino group due to the electron withdrawing para carbomethoxy functionality. [Pg.135]
