Procedure
A solution of 4-(4-fluorophenyl)-2-(piperidin-1-yl)-9H-fluorene-1-carbonitrile (368 mg) in THF was added sodium hydride (38 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. Red solid; mp 152-154° C.; ESIMS 383 (M++1); IR (KBr) 1708 cm−1 (CO), 2221 (CN); HRMS calcd. for C25H19 FN2O 382.1481 found 382.1471.
