The invention relates to novel benzo-fused heterocycles of structure (I) and their use as active ingredients in the preparation of pharmaceutical compositions. The invention also concerns related aspects including processes for the preparation of the compounds, pharmaceutical compositions containing one or more of those compounds and especially their use as endothelin receptor antagonists. Formula (I)

is presented. Methods traditionally used involve treatment of the 1,4-benzodiazepinone anion with an alkyl halide. It has been demonstrated that these derivatives can be methylated on the amide nitrogen atom by use of dimethyl-formamide dimethyl acetal which acts as both reagent and solvent for the reaction.
