Reaction Steps

To a solution of the compound (100 mg) obtained from step 3 above in dichloromethane (2 ml) at 0° C. was added trifluoroacetic acid (8 ml) and stirred the reaction mixture for about 2-3 hours and then at room temperature for 3 hours. The solvent and excess reagents were evaporated under reduced pressure and the residue thus obtained was purified by preparative thin layer chromatography (eluant-ethyl acetate) to furnish the title compound (40 mg).
