Nucleophilicsubstitution of 3‐bromo‐4‐phenyl‐1H‐[1,5]benzodiazepin‐2‐one (1) with thiourea or guanidine in presence of potassium carbonate afforded 1,5‐benzodiazepin‐3‐ylimidothiocarbamate 2 or 1,5‐benzodiazepin‐3‐ylguanidine 3, respectively. Pyrimidylthiobenzodiazepines 5, 6, 7, 8, 9, 10, 11, 12, 13 were obtained via the reaction of compound 2 with malononitrile dimer, diethyl malonate, methylenemalononitriles
