Reaction Steps

To a solution of the compound (40 mg) obtained from step 2 above in dry dichloromethane (10 ml) at 0° C. was added trifluoroacetic acid (0.5 ml) and anisole (0.05 ml) and stirred for 4 hours. The solvent and excess reagents were evaporated under reduced pressure and the residue thus obtained was purified by column chromatography using 60% ethyl acetate in hexane as eluant to furnish the title compound (25 mg).
