(S)-1′-(5-ethylpyrimidin-2-yl)-3-(methylamino)-1,4′-bipiperidin-2-one (0.040 g, 0.13 mmol), 1,2,4-trifluoro-5-(methylsulfonyl)benzene (Preparation C, 0.053 g, 0.25 mmol) and Na2CO3 (0.040 g, 0.38 mmol) were dissolved in DMF (1 mL) and heated at 130° C. overnight. The reaction was concentrated and the residue was purified using preparative TLC (100% EtOAc) to afford (S)-3-((2,5-difluoro-4-(methylsulfonyl)phenyl)(methyl)amino)-1′-(5-ethylpyrimidin-2-yl)-1,4′-bipiperidin-2-one (0.018 g, 0.035 mmol, 28% yield) as yellow solid. Mass spectrum (apci) m/z=508.3 (M+H).
