Reaction Steps

To a solution of Compound 56 (73 mg, 0.15 mmol) in AcOEt (6 ml) was added an excess amount of 10% HCl-MeOH (3 ml), and stirred for 18 h. After the solvent was evaporated in vacuo, the residual solid was recrystallized from MeOH-ether to give Compound 57 (48 mg, 78%) as a white solid.
