To a solution of crude 2-[3,5-bis(trifluoromethyl)phenyl]-N-4-[4-(4-fluoro-2-methylphenyl)-6-(octahydro-2H-pyrazino[1,2-a]pyrazin-2-yl)-3-pyridinyl]-N,2-dimethylpropanamide (D80, 100 mg, 0.16 mmol) in 5 mL of dichloromethane were added triethylamine (44 μL, 0.32 mmol, 2 eq.) and, at 0° C., methanesulfonyl chloride (18 μL, 0.24 mmol, 1.5 eq.). The reaction was left at room temperature overnight. Additional 3 eq. of methanesulfonyl chloride were added. It was then diluted with dichloromethane, extracted with sat. NaHCO3, the organics dried (Na2SO4), and the solvent was removed. The product was purified by flash chromatography (silica, EtOAc). Obtained 60 mg of the title compound.
