Reaction Steps

A mixture of 2-oxo-4-(piperidin-1-yl)-6-(thiophen-2-yl)-2H-pyran-3-carbonitrile (286 mg), indanone-2 (132 mg) and NaH (41 mg) in THF was stirred for <5 min. After completion, the reaction solvent was evaporated under vacuum to dryness and crude solid was quenched with ice water and subsequently neutralized with dil. HCl, finally purified by column chromatography using ethylacetate-hexane as eluent. White solid; mp 148-150° C.; FAB MS 357 (M++1); IR (KBr) 2215 cm−1 (CN), 1H NMR (200 MHz, CDCl3) δ 1.60-1.64 (m, 2H, CH2), 1.79-1.82 (m, 4H, 2CH2), 3.20-3.25 (m, 4H, 2CH2), 4.10 (s, 2H, CH2), 6.92 (s, 1H, ArH), 7.10-7.24 (m, 5H, ArH & CH), 7.49-7.54 (m, 2H, ArH & CH); HRMS calcd. for C23H20N2S 356.13472. Found 356,13580.
