反応手順
This compound was prepared in the same manner as the 4-thiocyano derivative described in Example XXXI except that the 4-t-butylazo-4-chloropentyl acetate was added to a slight molar excess of sodium azide in 70% aqueous methanol. The acetate was saponified by the addition of excess KOH to the reaction. The alcohol was then converted to the chloroformate by adding a pentane solution of the alcohol and pyridine to a pentane solution of phosgene. After workup the infrared spectrum confirmed that the alcohol was converted to the chloroformate.
