Reaction Steps

1-(1,4-Dioxa-spiro[4.5]dec-8-yl)-1H-[1,2,4]triazole (379 mg, 1.81 mmol) is dissolved in a 1:1 mixture of THF and 3N HCl aqueous solution (9 mL). The resulting mixture is stirred at 40° C. for 5 h. Most of the THF is removed under vacuum then the remaining mixture is neutralized using a 3N NaOH aqueous solution until a basic pH is reached. It is extracted with 3 portions of 10 mL of dichloromethane. The organic portions are combined, dried over anhydrous Na2SO4 and concentrated to afford 4-[1,2,4]triazol-1-yl-cyclohexanone as a white waxy solid.
