The reaction mixture was stirred for 18 h under nitrogen atmosphere. Cold water was added to the reaction mixture, the organic layer was separated. The reaction mixture was extracted with dichloromethane (3×5 mL). The combined organic layer was washed with water (2×5 mL). The organic layer was dried over sodium sulphate, and was concentrated. The crude product was purified by preparative HPLC [Eurospere-100, C18 column (250 mm×8 mm), mobile phase: acetonitrile-water (1:1 isocratic)] to obtain the title compound.
