Procedure

Farnesol (3.00 g, 13.5 mmol) was dissolved in methanol (30 ml), Pt/C (2%, 0.30 g) was suspended therein and the suspension was stirred overnight under a hydrogen atmosphere. After completion of the reaction, Pt/C was removed by filtration, and the filtrate was concentrated to give 3,7,11-trimethyldodecan-1-ol. This was used for the next reaction without purification.
