2-piperidin-4-yloxybenzonitrile

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 1-Boc-4-hydroxypiperidine (20 g, 99.35 mmol) and 2-cyanophenol (11.82 g, 99.35 mmol) were added to mixture of triphenylphosphine (26.06 g, 99.35 mmol) and di-tert-butyl azodicarboxylate (19.56 mL, 99.35 mmol) in tetrahydrofuran (800 mL) and the mixture was stirred at room temperature for 18 hours. The reaction mixture was then concentrated in vacuo and the residue was taken up in hydrochloric acid (4M in dioxane, 300 mL). The reaction mixture was stirred at room temperature for 18 hours and was then concentrated in vacuo. The residue was partitioned between water and ethyl acetate and the aqueous layer was separated and washed with ethyl acetate (2×100 mL). The aqueous solution was then basified with 2M sodium hydroxide solution and then extracted with diethyl ether (3×100 mL). The combined organic solution was dried over magnesium sulfate and concentrated in vacuo to afford the title compound as a white solid in quantitative yield. LRMS ESI m/z 203 [M+H]+. The reaction mixture was then concentrated in vacuo The reaction mixture was stirred at room temperature for 18 hours was then concentrated in vacuo The residue was partitioned between water and ethyl acetate the aqueous layer was separated washed with ethyl acetate (2×100 mL) extracted with diethyl ether (3×100 mL) The combined organic solution was dried over magnesium sulfate concentrated in vacuo
