To a solution of N-(4-(4-fluoro-2-methoxyphenyl)-6-methylpyridin-3-yl)-3-mercapto-N-methyl-5-(trifluoromethyl)benzamide (0.093 g, 206 μmol) in acetonitrile (2 mL) were added 3-iodooxetane (57.0 mg, 310 μmol) and DIPEA (66.7 mg, 90.1 μL, 516 μmol) and the clear, light yellow solution was heated under reflux for 2.5 hours. The reaction mixture was poured on saturated aqueous NH4Cl solution and EtOAc and the layers were separated. The aqueous layer was extracted twice with EtOAc. The organic layers were dried over MgSO4, filtered, treated with silica gel and evaporated. The compound was purified by silica gel chromatography on a 10 g column using an MPLC system eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). Colorless foam (0.05 g; 47%). MS (ESI): m/z=507.14 [M+H]+.
