An Efficient Tetrabutylammonium Fluoride (TBAF)-Catalyzed Three Component Synthesis
tion mixture was cooled to room temperature. Water was
added to it and then extracted with ethyl acetate (3ꢁ
10 mL). The organic phase was dried over anhydrous
Na2SO4, the solvent was evaporated under reduced pressure,
and the residue was purified by column chromatography
using hexane-ethyl acetate as eluent to afford the pure prod-
uct.
