Versuchsvorschrift

10 M aqueous NaOH (8.31 mL, 83 mmol) was added dropwise via addition funnel to a solution of nitromethane (4.46 mL, 83 mmol) and cyclohexanecarboxaldehyde (10 mL, 83 mmol) in EtOH (20 mL) at 0° C. with vigorous stirring. The resulting white slurry was stirred 10 minutes and became a white solid. Acetic acid (4.76 mL, 83 mmol) was added and the reaction was partitioned between diethyl ether and water. The layers were separated and the aqueous layer was extracted with diethyl ether. The combined organic extracts were washed with water, saturated aqueous sodium chloride, and dried over magnesium sulfate. The solution was filtered and concentrated in vacuo and dried under vacuum to afford 1-cyclohexyl-2-nitroethanol. The product was used directly for the next step without further purification.
