Procedure

The product from step 4 was dissolved in 5 mL of 4M HCl in dioxane and the mixture was stirred for 4 h. Ethyl acetate (10 mL) was added into the resulting mixture and washed with 2M Na2CO2 (2 mL). The resulting organic solution was dried over Na2SO4 and concentrated in vacuo. The residue was purified by preparative TLC.
