Reaction Steps

N-(5,6-Dihydrothiazolo[2,3-c][1,2,4]triazol-3-yl)-2-(3-(4-(4-methoxybenzoyl)piperidin-1-yl)-2-oxopyrrolidin-1-yl)acetamide (166 mg, 0.343 mmol) was eluted through a SCF column (70 mL/min flow rate) with 60% CO2 and 40% modifier (composed of 70% dichloromethane/ethanol and 0.2% diethylamine) to yield two enantiomerically enriched peaks N-(5,6-dihydrothiazolo[2,3-c][1,2,4]triazol-3-yl)-2-((S)-3-(4-(4-methoxybenzoyl)piperidin-1-yl)-2-oxopyrrolidin-1-yl)acetamide and N-(5,6-dihydrothiazolo[2,3-c][1,2,4]triazol-3-yl)-2-((R)-3-(4-(4-methoxybenzoyl)piperidin-1-yl)-2-oxopyrrolidin-1-yl)acetamide.
