4-(hydroxymethyl)oxane-4-carbonitrile

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

実験手順: Methyl 4-cyanotetrahydro-2H-pyran-4-carboxylate (2.93 g, 17.3 mmol) was dissolved in tetrahydrofuran (50 mL), methanol (10 mL) and water (5.0 mL). To this, sodium borohydride (1.31 g, 34.6 mmol) was added and the mixture was stirred at room temperature for 30 minutes. The reaction was stopped by addition of water to the reaction mixture, and extraction with ethyl acetate was performed, followed by washing with brine and drying over anhydrous sodium sulfate. The solvent was evaporated off under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate) to give 4-cyanotetrahydro-2H-pyran-4-ylmethanol (1.59 g, yield: 92%). by washing with brine drying over anhydrous sodium sulfate The solvent was evaporated off under reduced pressure the residue was purified by silica gel column chromatography (ethyl acetate)
