Procedure
To the MeOH solution (5 ml) of 8-[(E)-2-(2,2-dimethyl-[1,3]dioxolan-4-yl)-vinyl]-6,6-dimethyl-6H-benzo[b]naphtho[2,3-d]furan-11-one (125 mg), 10% Pd—C (25 mg) was added and the mixture was stirred overnight at room temperature under hydrogen atmosphere. The catalyst was removed by filtration. The residues obtained after concentration under reduced pressure were purified by HPLC to obtain the title compound (35 mg, 31%).
