YieldReaction ConditionsOperation in experiment
100%
Stage #1: With sodium tetrahydroborate In methanol at 0℃; for 2 h;
Stage #2: With ammonium chloride In ethyl acetate
To a solution of 3- bromothiophene-2-carbaldehyde (500 mg, 2.62 mmol) in methanol (10 mL) was added sodium borohydride (169 mg, 4.47 mmol) in small portions at 0 °C and the reaction was stirred for 2 firs. The solvent was evaporated and the residue partitioned between ethyl acetate (20 mL) and 10percent ammonium chloride solution (10 mL). The organic layer was washed with water (10 mL), dried over sodium sulfate and evaporated. The title compound (505 mg, 2.62 mmol, 100percent) was obtained as a yellow oil.
100% With sodium tetrahydroborate In methanol at 0℃; for 2 h; [00473] To a solution of 3-bromothiophene-2-carbaldehyde (6) (500 mg, 2.62 mmol) in methanol (10 mL) was added sodium borohydride (169 mg, 4.47 mmol) in small portions at 0 °C and the reaction was stirred for 2 hrs. The solvent was evaporated and the residue partitioned between ethyl acetate (20 mL) and 10percent ammonium chloride solution (10 mL). The organic layer was washed with water (10 mL), dried over sodium sulfate and evaporated. The title compound (505 mg, 2.62 mmol, 100percent) was obtained as a yellow oil.
92% With sodium tetrahydroborate In ethanol at 0 - 20℃; for 24 h; Inert atmosphere Stirring of 3-bromothiophene-2-carboxaldehyde (compound (2-1), 10 g, 52.3 mmol) / ethanol (EtOH, 200 mL) at 0 ° C under argon, and adding sodium borohydride (NaBH 4 , 3.4 g, 90.1 mmol) and stirred at room temperature for 24 hours. An aqueous solution of ammonium chloride was added to the oily solid obtained by concentration of the reaction mixture under reduced pressure, and the organic layer was extracted with ethyl acetate. After the extract was dried over magnesium sulfate and filtered, the filtrate was concentrated under reduced pressure to give a crude material. The crude product was purified by a silica gel column chromatography (ethyl acetate / hexane (volume ratio) = 2 / 8) to thereby obtain 3-bromothiophene-2-methanol (the compound (3-1), The yield was 9.3 g, and the yield was 92percent)
92% at 0 - 20℃; for 24 h; Inert atmosphere A solution of 3-bromothiophene-2-carboxaldehyde (compound (2-1), 10 g, 52.3 mmol) / ethanol (EtOH, 200 mL) was stirred at 0 ° C under an argon atmosphere, and sodium borohydride (NaBH 4 , 3.4 g, 90.1 mmol) and stirred at room temperature for 24 hours. An aqueous solution of ammonium chloride was added to the obtained oily solid, and the organic layer was extracted with ethyl acetate. After the extract was dried over magnesium sulfate and filtered, the filtrate was concentrated under reduced pressure to give a crude material. The crude product was purified by silica gel column chromatography (ethyl acetate / hexane (volume ratio) = 2/8), whereby 3-bromothiophene-2-methanol (the compound (3) -1), yield 9.3 g, yield 92percent).
