Procedure

At 0° C. sodium hydride (0.589 mg, 0.022 mmol) was added to a solution of cis-N-(2-(3-benzyl-6-fluoro-2-(3-hydroxy-3-methylazetidin-1-yl)-2,3-dihydro-1H-inden-5-yloxy)ethyl)-1-methyl-1H-imidazole-4-sulfonamide (9.1 mg, 0.018 mmol; see example 206) in dry tetrahydrofuran (1 ml). The obtained suspension was stirred for 30 min at 0° C. and 1 h at room temperature. After dropwise addition of methyl iodide (1.216 μl. 0.019 mmol) the reaction mixture was stirred for 5 h and poured on a mixture of sat. ammonium chloride/ethyl acetate. The organic layer was separated and the aqueous layer washed twice with ethyl acetate. The combined organic layers were washed with sat. ammonium chloride, water and brine, dried over magnesium sulfate, filtered and evaporated to obtain the crude product as a pale yellow oil, that was purified on 1.5×5 cm SiO2-column using 5% methanol in dichloromethane to afford N-(2-(3-benzyl-6-fluoro-2-(3-hydroxy-3-methylazetidin-1-yl)-2,3-dihydro-1H-inden-5-yloxy)ethyl)-N,1-dimethyl-1H-imidazole-4-sulfonamide as clear oil. m=3.1 mg (33%)
