Procedure

(S)-3-(4-bromo-2-fluoro-5-methylphenoxy)-1-(piperidin-4-yl)pyrrolidin-2-one hydrochloride (600 mg, 1.47 mmol) was dissolved in DMSO (10 mL) and N-ethyl-N-isopropylpropan-2-amine (641 μl, 3.68 mmol) and 2-chloro-5-ethylpyrimidine (252 mg, 1.77 mmol) were added and the reaction heated to 110° C. overnight. The reaction was cooled to ambient temperature, poured into water and extracted with EtOAc, dried over Na2SO4, filtered and concentrated. The residue was purified over silica gel (60% EtOAc in hexanes) to afford (S)-3-(4-bromo-2-fluoro-5-methylphenoxy)-1-(1-(5-ethylpyrimidin-2-yl)piperidin-4-yl)pyrrolidin-2-one (420 mg, 0.880 mmol, 59.8% yield) as a tan solid.
