A method for the oxidative coupling of arylsilanes with nitrogen nucleophiles is reported. This method occurs with a broad range of heptamethyltrisiloxylarenes and nitrogen nucleophiles, proceeds with the arylsilane as limiting reagent, and does not require a fluoride activator with electron-poor arylsilanes. The combination of this method with C–H silylation generates arylamines from unactivated arenes
The invention is concerned with novel 4-aminomethyl benzamidine derivatives of formula (I)
wherein Ar and X are as defined in the description and in the claims, as well as prodrugs and pharmaceutically acceptable salts thereof These compounds inhibit the formation of coagulation factors Xa, IXa and thrombin induced by factor VIIa and tissue factor and can be used as medicaments.
