4-(二甲氨基)苄醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Mix 4-(dimethylamino)benzyl alcohol (3.35 g. 22 mmol), 3-hydroxybenzaldehyde (2.69 g, 22 mmol), triphenylphosphine (5.8 g, 22 mmol) and diethylazadicarboxylate (3.83 g, 22 mmol) in tetrahydrofuran (25 mL). Stir at room temperature under anhydrous atmosphere until the reaction is done. Concentrate the solution in vacuo and dilute with a small quantity of ethyl ether. Filter any precipitate and concentrate the filtrat in vacuo. Purify by silica gel chromatography to give 3-(4-(dimethylamino)-benzyloxy) benzaldehyde. Concentrate the solution in vacuo dilute with a small quantity of ethyl ether Filter any precipitate concentrate the filtrat in vacuo Purify by silica gel chromatography

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Mix 4-dimethylaminobenzaldehyde (3.3 g, 22 mmol), sodium borohydride (830 mg, 22 mmol) and absolute ethanol (25 mL). Stir at room temperature until the reaction is complete, pour onto dilute hydrochloric acid and extract into ethyl acetate. Separate the organic phase and extract the aqueous phase with ethyl acetate (2×). Combine the organic phases and dry (MgSO4). Evaporate the solvent in vacuo and purify by silica gel chromatography to give 4-(dimethylamino)benzyl alcohol. extract into ethyl acetate Separate the organic phase extract the aqueous phase with ethyl acetate (2×) Combine the organic phases and dry (MgSO4) Evaporate the solvent in vacuo purify by silica gel chromatography
