実験手順

To a solution of (3aR*,10aS*)-9-[4-(benzyloxycarbonylamino)benzyl]-2,3,3a,4,9,10a-hexahydrobenzo[b]cyclopenta[e][1,4]diazepin-10(1H)-one (610 mg, 1.4 mmol) in dichloromethane (7 mL) was added bromoacetyl bromide (0.15 mL, 1.7 mmol) dropwise and the mixture was stirred at room temperature for 15 minutes. This reaction mixture was diluted with water (5 mL) with vigorous stirring and neutralized with sodium hydrogen carbonate. The aqueous layer was separated and the organic layer was washed with water, dried over MgSO4, filtered, and concentrated under reduced pressure. The residue was recrystallized from chloroform-ethyl acetate to provide 519 mg (yield 66%) of the title compound. m.p. 222°-223° C. (decomp.).
