Reaction Steps

The compound (160 mg, 0.45 mmol) obtained in Step 3 was dissolved in a mixture of an aqueous solution of potassium carbonate (91 mg, 0.66 mmol) in water (1 ml) and methanol (2 ml) and the mixture was stirred at 70° C. for 3 hours. The reaction mixture was acidified by adding concentrated hydrochloric acid and then was extracted with diethylether. The extract was washed with water, dried, and then the solvent was distilled off to yield the title compound (116 mg, 0.34 mmol, yield 76%).
