Methanol → HCID 178444111, compound

Participants

Reaction Steps

A solution of 1-cyano-1-(trans-4-methoxycyclohexyl)-4-decanone (48) (5.1 g, 17.4 mmol) obtained in the second step dissolved in 100 mL of THF and 50 mL of methanol was cooled with ice, to which sodium borohydride (0.79 g, 20.9 mmol) was then gradually added, followed by stirring under cooling with ice for 1 hour. The reaction mixture was put in 100 mL of iced water, and then extracted with 100 mL of ethyl acetate. The resulting organic layer was washed with water (100 mL×2) and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The resulting residue was purified by column chromatography (developing solvent: heptane/ethyl acetate=4/1, column packing: silica gel) to obtain 1-cyano-1-(trans-4-methoxycyclohexyl)-4-decanol (49) (5.1 g, 17.4 mmol). The resulting compound was in the form of colorless crystals, and the yield based on the compound (48) was 100%.
