Versuchsvorschrift

171 mg (1.46 mmol) of isopentyl nitrite and 196 mg (1.46 mmol) of copper(II) chloride were initially charged in 18 ml of acetonitrile. 389 mg (0.73 mmol) of the compound from Example 40A were added, and the mixture was then stirred at 60° C. for 3 h. After cooling to RT, 20 ml of 1N hydrochloric acid were added. The aqueous phase was extracted twice with in each case 30 ml of ethyl acetate. The combined organic phases were dried over magnesium sulfate. The solvent was removed, and the product was then used without further purification for the subsequent reaction.
