실험 절차

To (S)-1-(2-hydroxyethyl)-4-isopropyl-3-(3-(4-(1-((2-(trimethylsilyl)ethoxy)methyl)-1H-1,2,4-triazol-3-yl)phenyl)pyrazolo[1,5-a]pyrimidin-5-yl)imidazolidin-2-one (0.18 g, 0.32 mmol) was added trifluoroacetic acid (5 mL) and the reaction was stirred at ambient temperature for 3 hours. The reaction was concentrated in vacuo and the material purified by reverse preparative HPLC to yield the crude product and the corresponding trifluoroacetate ester. To this material was added 1N NaOH/MeOH and the mixture stirred at ambient temperature for 2 hours. The mixture was concentrated in vacuo. The combined crude product was purified by reverse preparative HPLC to give (S)-3-(3-(4-(1H-1,2,4-triazol-3-yl)phenyl)pyrazolo[1,5-a]pyrimidin-5-yl)-1-(2-hydroxyethyl)-4-isopropylimidazolidin-2-one (0.0061 g, 0.014 mmol, 4.4% yield) as the mono TFA salt. LCMS (APCI+) m/z 433 [M+H]+.
