Acetonitrile → N-(2-(3-benzyl-6-fluoro-2-(3-methylazetidin-1-yl)-2,3-dihydro-1H-inden-5-yloxy)ethyl)-1-methyl-1H-imidazole-4-sulfonamide

Participants

Reaction Steps

To N-(2-(2-amino-3-benzyl-6-fluoro-2,3-dihydro-1H-inden-5-yloxy)ethyl)-1-methyl-1H-imidazole-4-sulfonamide (20.7 mg, 0.047 mmol), 10 equivalents 1-bromo-3-chloro-2-methylpropane and potassium carbonate(70.8 mg) in water (1 mL) +1 drop acetonitrile were added. Microwave at 120° C. Evaporated acetonitrile, re-dissolved in dichloromethane and extracted with water and brine, dried over sodium bicarbonate, filtered and evaporated to obtain the crude product and was purified by flash silica gel chromatography on 4 g SiO2-cartridge using 10% methanol in dichloromethane to afford N-(2-(3-benzyl-6-fluoro-2-(3-methylazetidin-1-yl)-2,3-dihydro-1H-inden-5-yloxy)ethyl)-1-methyl-1H-imidazole-4-sulfonamide as a clear glass m=2.0 mg (8.6%)
