Reaction Steps

(2S)-2-(Trifluoromethyl)pyrrolidine (858 mg, 6.17 mmol) was dissolved in THF (10 mL) in a 250 mL RB flask. The mixture was cooled in an ice bath. Then molecular sieves were added and let stir for 5 minutes. LiHMDS (6.78 mL, 6.78 mmol) was added slowly followed by addition of 4,6-dichloro-2-(methylthio)pyrimidine (1.444 g, 7.40 mmol), and the reaction was stirred at 0° C. for an additional 10 minutes. Then water (10 mL) was added followed by dropwise addition of 6N HCl until pH was acidic. The mixture was then extracted with EtOAc (3×30 mL) and the organic was combined, washed with saturated NaCl, filtered and concentrated. The crude oil was purified on Biotage 25 g SNAP column with a gradient of 0 to 35% EtOAc in Hexane over 25 minutes to afford the title compound (1.42 g) as a clear oil. LC-MS (ES) m/z=298 [M+H]+.
