実験手順
Following General Procedure D above using 1-(S)-[L-alaninyl]-amino-3-methyl-4,5,6,7-tetrahydro-2H-3-benzazepin-2-one hydrochloride (Example 7-30, below) and 2-(N-Boc-amino)-4,4,4-trifluorobutyric acid (Oakwood), the protected intermediate was prepared. The Boc-group was removed using 5.0 M HCl in dioxane and the resulting free-base purified by flash chromatography CHCl3/MeOH (97.3) yielding the title compounds.
