Ethyl Acetate → HCID 13220943, compound

Participants

Reaction Steps

A solution of 6.00 g (0.032 mole) of the 2-phenylacetylpyrrole (III) in 200 ml of anhydrous tetrahydrofuran was added to a suspension of 600 g (0.153 mole) of lithium aluminum hydride in dry tetrahydrofuran. The mixture was stirred at reflux temperature for 48 h. The mixture was cooled to 0°, ethyl acetate was cautiously added to destroy the excess hydride and then saturated aqueous sodium sulfate was added. The organic phase was decanted, dried over sodium sulfate and evaporated in vacuo. The residue was subjected to column chromatography on neutral alumina (Fluka, Act II). 4.800 g (88%) of 2-[phenethyl]pyrrole (IV) was eluted with hexane-ethyl acetate and crystallized, m.p. 40°-42° (hexane). (Step 2).
