실험 절차

(2S,3R)-3-amino-2-methyl-2,3-dihydro-1,5-benzoxazepin-4(5H)-one trifluoroacetate salt was prepared from (2S,3R)-3-t-butyloxycarbonylamino-2-methyl-2,3-dihydro-1,5-benzoxazepin-4(5H)-one (Robl, et al., Bioorg. & Med. Chem. Lett. 1994, 4, 1789–1794) by treatment with a solution of trifluoroacetic acid-dichloromethane-tetrahydrofuran (1:10:10) at room temperature, followed by solvent evaporation and coevaporation with tetrahydrofuran under vacuum.
