반응 단계
A mixture of (3RS)-3-amino-1-[(3-azabicyclo[3.2.2]non-3-yl]carbonylmethyl]-2,3-dihydro-5-(2-fluorophenyl)-1H-1,4-benzodiazepin-2-one (1.2 g) and carbonyldiimidazole (895 mg) was stirred at room temperature overnight. Ethyl acetate and water were added to the reaction mixture, and organic layer was separated, washed with water and brine, dried over magnesium sulfate, and evaporated in vacuo. The amorphous powder was washed with isopropyl ether to afford (3RS)-1-(3-azabicyclo[3.2.2]non-3-yl)carbonylmethyl-2,3-dihydro-3-(imidazol-1-yl) carbonylamino-5-(2-fluorophenyl)-1H-1,4-benzodiazepin-2-one (1.43 g).
