Procedure

A mixture of Novozym 435 (2.81 g), molecular sieves (23.17 g), 3,7-dimethyl-1-octanol (4.64 g), and ethyl lactate (14.78 g) in a 250 mL beaker was maintained at 60° C. in a convection oven for 28 hours. Upon work-up, 4.2 g of 3,7-dimethyl-1-octyl lactate (62% yield) was obtained as an amber-colored liquid. The purity of the product was >96% as assessed by HPLC-RI.
