Reaction Steps

A mixture of 3-methylpyrrolidin-3-ol (1.41 g, 13.9 mmol), (R)-1-(6-chloropyridin-3-yl)-2,2,2-trifluoroethyl trifluoromethanesulfonate (4.30 g, 12.5 mmol) and K2CO3 (1.93 g, 13.9 mmol) in THF (69.7 mL, 13.9 mmol) was heated in a sealed tube to 50° C. overnight. The reaction was filtered, concentrated under reduced pressure and the residue was purified by preparative HPLC (C18, 300 g, 10% MeCN/water to 95% MeCN/water over column volumes) to give 1-((S)-1-(6-chloropyridin-3-yl)-2,2,2-trifluoroethyl)-3-methylpyrrolidin-3-ol (2.01 g, 48.9% yield).
