Procedure

To N-(2-(2-amino-3-benzyl-2,3-dihydro-1H-inden-5-yloxy)ethyl)-1-methyl-1H-imidazole-4-sulfonamide (35.4 mg, 0.083 mmol; see example 193), 1,3-dibromopropane and potassium carbonate(12.62 mg, 0.091 mmol) in water (1 mL)+1 drop acetonitrile were added. Microwave at 120° C. for 20 min. 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 obtain N-(2-(2-(azetidin-1-yl)-3-benzyl-2,3-dihydro-1H-inden-5-yloxy)ethyl)-1-methyl-1H-imidazole-4-sulfonamide as a clear glass. m=3.1 mg (8%)
