Procedure

4-cyclopentyl-3-methylbutyl acetate (1.98 kg, 10.0 mols, purity: 98%) sodium hydroxide (420 g, 10.5 mols) and water (8400 ml) were mixed together and heated at 90-95° C. under stirring for 10-12 h. The reaction mixture was cooled to 35° C. The aqueous phase was separated from the organic phase. The organic phase was washed once with 5% w/w aqueous NaCl and twice with water. The crude product was fractionated under reduced pressure to provide 4-cyclopentyl-3-methylbutan-1-ol (1.43 kg, yield: 92%; GC purity: 99%).
