Reaction Steps

To an ice-cold solution of 3-(azetidin-3-ylsulfonyl)-N-(4-(4-fluoro-2-methoxyphenyl)-pyridin-3-yl)-N-methyl-5-(trifluoromethyl)benzamide (0.05 g, 95.5 μmol, example 280) and DIPEA (24.7 mg, 33.4 μL, 191 μmol) in CH2Cl2 (1 mL) was added methanesulfonyl chloride (16.4 mg, 11.2 μL, 143 μmol) and stirring was continued in an ice-bath for 1.75 hours. The reaction mixture was poured on saturated aqueous NH4Cl solution and CH2Cl2 and the layers were separated. The aqueous layer was extracted twice with CH2Cl2. The organic layers were dried over MgSO4, filtered, treated with silica gel and evaporated. The compound was purified by silica gel chromatography on a 5 g column using an MPLC system eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). Colorless solid (0.044 g; 76%). MS (ESI): m/z=602.10 [M+H]+.
