实验步骤: The hydrazide of (1S,2R)-2-hydroxymethyl-1-cyclohexanecarboxylic acid (0.5 gram) is reacted with a solution of 0.5 grams of sodium nitrite in 10 ml of 5% H2SO4. The reaction mixture is maintained for 1 hour at 0-5° C., followed extraction of the reaction mixture with ethyl acetate, followed by basification of the resulting aqueous solution with NaOH, extraction with methyl t-butyl ether, drying of the extracts over MgSO4, filtration, and the removal of solvent by rotary evaporation. The product (1S,2R)-1-amino-2-(hydroxymethyl)cyclohexane is isolated as a light yellow oil. extraction of the reaction mixture with ethyl acetate followed by basification of the resulting aqueous solution with NaOH, extraction with methyl t-butyl ether drying of the extracts over MgSO4, filtration the removal of solvent by rotary evaporation
