실험 절차

The Grignard reagent prepared from iodomethane (14.2 g., 0.1 mole) and magnesium (2.4 g., 0.1 mole) in ether solution is added, dropwise to an ether solution of 1-chloro-4-nonanone (Example A, Step 1) (17.6 g., 0.1 mole). The reaction is refluxed gently for 3 hours then cooled and poured carefully into ice water (300 ml.). The ether layer is separated, washed with brine, and dried over sodium sulfate. Removal of the ether in vacuo gives 1-chloro-4-hydroxy-4-methylnonane as an oil. The tertiary alcohol is dissolved in pyridine and treated with one molar equivalent of acetic anhydride at 60°-80° for 8-16 hours to give 1-chloro-4-acetoxy-4-methylnonane as a colorless oil.
