実験手順

To a solution of ester from Step 5 (3.5 g, 7.6 mmol) in MeOH/THF (50 mL/35 mL) was added 1M NaOH (22.9 mL, 22.9 mmol). After heating at reflux for 2 h, the mixture was concentrated under vacuum and the residue was partitioned between EtOAc/H2O containing HOAc (3 mL). The organic layer was washed with H2O, brine, and was then dried (MgSO4), filtered, and evaporated. The resulting solid was stirred vigorously with 1:10 EtOAc/hexane for 2 h to give, after filtration, 2.81 g of white solid.
