Participants

Reaction Steps

A mixture of 5-(2-fluoro-6-hydroxyphenyl)-3-methyl-1-(4-(trifluoromethoxy)benzyl)pyrrolidin-2-one (preparation described in example 413; 50 mg; 0.13 mmol), 1-fluoro-2-iodoethane (23 mg; 0.13 mmol), potassium carbonate (36 mg; 0.26 mmol), and cesium carbonate (8.5 mg; 0.026 mmol) in anh. DMF (0.7 ml) was stirred at rt, under nitrogen, for 17 h. Subsequent filtration and purification by preparative HPLC afforded the target compound. LC-MS (conditions A): tR=0.92 min.; [M+H]+: 429.96 g/mol.
