Participants

Reaction Steps

20 mg (0.042 mmol) of [4-(4-chlorobenzoyl)-2-oxo-2,3,4,5-tetrahydrobenzo[e][1,4]diazepin-1-yl]acetic acid trifluoroacetate was dissolved in 2 ml of dichloroethane. 5 mg (0.055 mmol) of 3-aminopyridine, 11 mg (0.055 mmol) of 2-chloro-1,3-dimethylimidazonium chloride and 0.018 ml (0.126 mmol) of triethylamine were added to the obtained solution, and they were stirred overnight. The solvent was evaporated, and the obtained crude product was treated in the same manner as in step 3 in Example 1 to obtain the title compound.
