실험 절차
On completion of the bioreduction stage the fermentation broth was centrifuged at 5000 rpm for 20 minutes at 20-22° C. The compound of formula (III) (R=t-butyl) was isolated from the supernatant by extraction with a suitable organic solvent such as toluene, isoamyl acetate, 2-pentanone, ethyl acetate or 4-methyl-2-pentanone, preferably ethyl acetate or 2-pentanone. The solvent extract was dried over anhydrous sodium sulphate and the solvent removed by vacuum distillation to afford the crude product of formula III (R=t-butyl) as a golden oil.
