Trifluoroacetic acid (1 mL) and water (0.5 mL) were added to the compound obtained from step k above (0.04 g). The reaction mixture was stirred at room temperature for 2 hours. The solvents were evaporated at reduced pressure. The residue thus obtained was taken in ethyl acetate and water. The organic layer was separated, washed with water and brine solution, and dried over anhydrous sodium sulphate. The solvent was concentrated under reduced pressure to yield the title compound (0.028 g).
