Procedure

To a solution of triphenylphosphine (110 mmg, 0.4 mmol) in 0.7 mL of tetrahydrofuran is added diisopropyl azodicarboxylate (0.08 mL, 0.4 mmol) and the reaction stirred for 30 min. To the reaction is added 0.4 mL of tetrahydrofuran, (2-(4-chloro-benzenesulfonylamino)-3-phenyl-propionamide (75 mg, 0.2 mmol), and methyl-4-hydroxybenzoate (73 mg, 0.4 mmol). The reaction is allowed to warm to room temperature (rt) and stirred overnight. The solvent is removed and the resultant residue purified by silica gel chromatography to provide the title compound.
