実験手順

To a 250 mL round bottomed flask containing DMF (50 mL) was added 4-bromo-2-cyclopropyl-6-nitro-1H-benzo[d]imidazole (4.3 g, 15.24 mmol), 1-(bromomethyl)-2-methyl-3-(trifluoromethyl)benzene (3.6 mL, 21.34 mmol) and potassium carbonate (6.32 g, 45.7 mmol). The resultant suspension was heated to 50° C. and after stirring for 30 minutes the mixture was allowed to cool to rt and diluted with 100 mL H2O. The mixture was stirred overnight and the next day a brown filterable solid was isolated by filtration providing crude 4-bromo-2-cyclopropyl-1-(2-methyl-3-(trifluoromethyl)benzyl)-6-nitro-1H-benzo[d]imidazole (5.97 g, 13.14 mmol, 86% yield). MS (ES+) m/e: 453.0, 454.0 [M+H]+
