Reaction Steps

A solution of 2-(piperidin-1-yl)-4-p-tolyl-9H-fluorene-1-carbonitrile (364 mg) in THF was added sodium hydride (40 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 230-232° C.; ESMS 379 (M++1); IR (KBr) 1703 cm−1 (CO), 2219 (CN); 1H NMR (300 MHz, CDCl3) δ 1.60-1.64 (m, 2H, CH2), 1.79-1.84 (m, 4H, 2CH2), 2.48 (s, 3H, CH3), 3.19-3.24 (m, 4H, 2CH2), 6.65-6.70 (m, 1H, ArH), 6.87 (s, 1H, ArH), 7.14-7.19 (m, 2H, ArH), 7.28-7.33 (m, 4H, ArH), 7.63-7.67 (m, 1H, ArH). HRMS calcd. for C26H22N2O 378.1732 found 378.1728.
