Procedure

A procedure similar to that described in Example 18-6) was performed with 2-(3,3-diethoxycarbonylpropyl)-4-tert-butoxycarbonylaminomethylaniline (559 mg, 1.37 mmol) and (S)-9-chloro-5-carboxymethyl-6,7-dihydro-1H, 5H-pyrido[1,2,3-de]quinoxaline-2,3-dione (445 mg, 1.51 mmol) to give 735 mg of the title compound after silica gel column chromatography with 0.3% acetic acid/ethyl acetate (78%).
