実験手順

The phthalimide protected amine, N—[(R)-1-(1-benzyl-4,5-dimethyl-6-oxo-1,6-dihydro-pyrimidin-2-yl)-2-methyl-propyl]-N-[2-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-ethyl]-4-methyl-benzamide, (0.075 g, 0.13 mMol) was treated with hydrazine monohydrate (0.013 mL, 0.26 mMol) in ethanol (1 mL) at 70° C. for 12 h. The reaction was filtered, concentrated under vacuum and dissolved in toluene (1 mL) and heated to 120° C. for 20 h. The reaction was concentrated under vacuum, taken up in CH3CN and purified by reverse phase HPLC (YMC, ODS-A, 20 min, 5-90% gradient, CH3CN:H2O, 0.1% TFA) The fractions were collected and evaporated to give the title compound as a clear oil. (0.016 g): MS (ES) m/e 429.4 (M+H)+.
