Procedure

To a solution of (2S,3S)-3-amino-2-phenyl-2,3-dihydro-1,5-benzothiazepin-4(5H)-one hydrobromide (9d) (91 mg) in 10 mL of THF was added Fmoc-Phe-Opfp (185 mg) followed by DIEA (58 μL). The reaction mixture was stirred for 30 min and treated with DBU (0.1 mL) and stirred for 10 min. The material thus produced was used in the next step without purification or characterization.
