A mixture of 4-(3-bromoacetyl-phenyl)-8-chloro-7-dimethylamino-1,3-dihydro-benzo[b][1,4]diazepin-2-one (130 mg) (Example 193a) and N-amidino-thiourea (35 mg) in THF (3 mL) was heated at 60° C. for 1 h. The mixture was diluted with AcOEt and washed with sat. NaHCO3 solution and with brine. The organic layer was dried and evaporated and the residue was purified by chromatography on silica gel using AcOEt/MeOH (20:1) as eluent. The purified product was crystallyzed from acetone to give the title compound (22 mg) as yellow solid.
