Ethanol → HCID 21914400, compound

Participants

Reaction Steps

4-Bromoacetophenone (1.95 g), piperidine (0.97 ml) and titanium(IV) isopropoxide (3.64 ml) were stirred under argon at room temperature for 1 h. Ethanol (10 ml) was added, followed by sodium cyanoborohydride (0.41 g) and mixture stirred for 18 h. Water (2 ml) was then added and the mixture stirred for 20 minutes. The resulting inorganic precipitate was filtered off, washed with ethanol (20 ml) and the combined organic phase was concentrated in vacuo, redissolved in toluene and purified by Bondelute® chromotography, eluting with 0–20% ethyl acetate/iso-hexane to give the product as a pale yellow oil (1.07 g).
