実験手順

To a solution of the product from step D (15 mg, 0.028 mmol, enantiomer A) in EtOH (2 mL) was added 2N HCl (0.5 mL). The mixture was stirred at 50° C. overnight. The volatile was removed under reduced pressure and the residue was purified by Combiflash (Mobile phase: MeOH/H2O (0.08% of NH4HCO3) to obtain the title compound.
