실험 절차

This compound was prepared by esterifying 32 g (0.25 mole) of the product from Example 3 with 24 g (0.3 mole) of acetyl chloride and 24 g (0.3 mole) of pyridine at from 15° to 20° C. On working up in the conventional manner, the ester was obtained in 95% yield; boiling point: 88°-90° C/25 mm Hg; nD25 : 1.4743; the structure was confirmed by the nuclear resonance spectrum. Fragrance: musk-like, floral; good tenacity.
