Reaction Steps

To a solution of Diastereomer 1 of 1-((S)-1-(6-chloropyridin-3-yl)-2,2,2-trifluoroethyl)-3-methylpyrrolidin-3-ol (0.550 g, 1.866 mmol) in sec-butanol (10 mL) was added hydrazine (0.8786 mL, 27.99 mmol) and stirred at 125° C. overnight. The reaction was concentrated from methanol (3×30 mL) to give Diastereomer 1 of 3-methyl-1-((S)-2,2,2-trifluoro-1-(6-hydrazinylpyridin-3-yl)ethyl)pyrrolidin-3-ol (0.580 g, 1.998 mmol, 107.1% yield).
