Procedure

To a suspension of N-(4-(4-fluoro-2-methoxyphenyl)pyridin-3-yl)-3-mercapto-N-methyl-5-(trifluoromethyl)benzamide (0.1 g, 229 μmol, example 216, intermediate a) in acetonitrile (2 mL) were added tert-butyl 2-bromoethylcarbamate (56.5 mg, 252 μmol) and DIPEA (59.2 mg, 80.0 μL, 458 μmol). After the addition of DIPEA the white suspension turned to a yellow solution, which was stirred at room temperature for 3 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 (0.111 g; 83%). MS (ESI): m/z=580.19 [M+H]+.
