Reaction Steps

To a solution of (S)-3-(6-(methylsulfonyl)pyridin-3-yloxy)-1-(piperidin-4-yl)pyrrolidin-2-one hydrochloride salt (100 mg, 0.26 mmol) and DIEA (0.324 mL, 1.86 mmol) in DMF (3 mL) was added 2-chloro-5-ethylpyrimidine (76 mg, 0.532 mmol). The reaction was heated to 100° C. for 4 hours at which point the reaction was poured into water (10 mL) and EtOAc (10 mL). The organic layer was separated and the aqueous layer extracted with EtOAc (2×5 mL). The combined organic layers were dried with MgSO4 and concentrated in vacuo. The resulting material was purified by silica gel chromatography eluting with 1:1 hexanes/EtOAc to EtOAc to yield (S)-1-(1-(5-ethylpyrimidin-2-yl)piperidine-4-yl)-3-(6-(methylsulfonyl)pyridine-3-yloxy)pyrrolidin-2-one (35 mg, 30%) as an off white solid. Mass spectrum (apci) m/z=452.2 (M+H).
