실험 절차

A suspension of N-(3-Hydroxy-phenyl)-acetamide (30.2 g) in anhydrous tetrahydrofuran (600 mL) was treated with 4-hydroxy-N-methylpiperidine (30.54 mL) and triphenylphosphine (68.18 g); a solution of diethylazadicarboxylate in anhydrous tetrahydrofuran (THF) (40.94 mL in 60 mL of THF) was added dropwise and the mixture was stirred at room temperature for 2 hours and then heated to 50° C. overnight. Further amounts of triphenylphosphine (28.00 g) and diethylazadicarboxylate (14 mL) were added and the heating was continued for additional 24 hours.
