Versuchsvorschrift

To a solution of 1-(4-fluorophenyl)-5-tetrazol-5-yl-1H-indole (8a) (19 g) in NMP (200 mL) potassium t-butoxide (8.5 g) was added cautiously at 10° C. followed by dropwise addition of iodomethane (22 g) during 20 minutes. The mixture was allowed to reach room temperature and stirred for another 2 hours. Crude title compound was worked up according to the general procedure above. Purification was performed by column chromatography on silica gel using dichloromethane as eluent. Yield 15 g, mp 131-133° C.
