Versuchsvorschrift

To a solution of N-(4-(2-hydroxyphenyl)-6-methylpyridin-3-yl)-N-methyl-3-(methylsulfonyl)-5-(trifluoromethyl)benzamide (100 mg, 215 μmol) in DMF (2 mL) was added K2CO3 (59.5 mg, 431 μmol) and 3-iodooxetane (43.6 mg, 237 μmol). The reaction mixture was stirred for 2 hours at room temperature followed by stirring for 18 hours at 80° C. The reaction mixture was poured on 30 mL 10% aqueous NaHCO3 solution and 30 mL EtOAc and the layers were separated. The aqueous layer was extracted a second time with 30 mL EtOAc. The organic layers were washed with 30 mL brine, dried over MgSO4, filtered and concentrated under vacuum. The compound was purified by silica gel chromatography on a 10 g column using an MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane:EtOAc (100:0 to 0:100). Colorless solid (30 mg, 27%). MS (ESI): m/z=521.134 [M+H]+.
