Procedure

The compound of Example 1G (36 mg) was dissolved in 0.3 mL of a solution of TsOH.H2O/CH2Cl2/THF (1.9 g/3 mL/3.8 mL); the resultant mixture was stirred at room temperature for 3 hours. The reaction mixture was added dropwise to NaHCO3 solution (2 mL, saturated) and then extracted with EtOAc (3 times). The combined organic layer was washed with brine, dried over Na2SO4 and concentrated. The crude product was purified by preparative TLC to provide the title compound (20 mg, 74% yield).
