Reaction Steps

12.95 g of [1R-[1α[1R*,4S*-(E)],3aβ,4α,7aα]]-octahydro-7a-methyl-1-(1,4,5-trimethyl-2-hexenyl)-1H-inden-4-ol 1 is introduced into 220 ml of dimethylformamide [H. H. Inhoffen et al. Chem. Ber. 91, 781 (1958)], 5.33 g of imidazole and 10.78 ml of chlorotriethylsilane are added, and it is stirred for 24 hours at room temperature. It is quenched with sodium chloride solution, extracted with ethyl acetate, the organic phase is washed with sodium chloride solution and dried on sodium sulfate. After the solvent is removed, the residue is purified by chromatography on silica gel with ethyl acetate/hexane, whereby 14.6 g of title compound 2 is obtained as a colorless oil.
