Versuchsvorschrift

A solution of 1-(naphthalen-2-yl)-3-(piperidin-1-yl)-9H-fluorene-4-carbonitrile (400 mg) in THF was added sodium hydride (39 mg) and was stirred at 0-5° C. for less than five minutes. After completion, the reaction solvent was evaporated under vacuum and the crude solid obtained was quenched with ice water and subsequently neutralized by dilute HCl. The precipitate thus obtained was filtered and purified on a silica gel column using ethyl acetate-hexane as eluent. Yellow solid; mp 166-167° C.; ESIMS 415 (M++1); IR (KBr) 2218 (CN), 1712 cm−1 (CO); HRMS calcd. for C9H22N2O 414.1732. Found 414.1735.
