Reaction Steps

A mixture of 2-oxo-6-phenyl-4-(pyrrolidin-1-yl)-2H-pyran-3-carbonitrile (266 mg), indanone-1 (132 mg) and NaH (31 mg) in THIF 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 158-160° C.; ESIMS 336 (M+); IR (KBr) 2203 cm−1 (CN); 1H NMR (200 MHz, CDCl3) δ 2.01-2.05 (m, 4H, 2CH2), 3.68-3.72 (m, 4H, 2CH2), 3.78 (s, 2H, CH2), 6.63 (s, 1H, ArH), 7.30-7.51 (m, 8H, ArH), 8.63 (d, J=7.8 Hz, 1H, ArH); HRMS calcd. for C24H20N2 336.1627. Found 336.1599.
