الإجراء التجريبي

Amide 132 (345 mg, 175 μmol) was dissolved in MeOH/THF 1:1 (16 mL). NaOMe (500 μL of a 6M solution) was added and the solution was stirred at room temperature for 24 hrs. The mixture was neutralized with acidic resin and the solution filtered before the solvent was evaporated to yield the white solid product which was triturated with EtOAc and the solvent decanted (×3). The solid was dried under vacuum to yield 124 mg of the white solid product (76%) which was reacted on without further purification or characterisation.
