Procedure

To a solution of N-(2-nitrobenzenesulfonyl)-N-(2-pyridinylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (251 mg, 0.46 mmol) and N-(tert-butoxycarbonyl)-L-alanine (97 mg, 0.51 mmol) in CH2Cl2 (5 mL) was added N,N-diisopropylethylamine (0.24 mL, 1.38 mmol), 1-hydroxybenzotriazole hydrate (81 mg, 0.60 mmol) and 1-(3-dimethylaminopropyl)-3-ethyl carbodiimide HCl (EDC) (116 mg, 0.61 mmol) and the mixture was stirred at room temperature for 15 hours. The reaction was worked-up as described above to give the crude amide as a mixture of diastereomers. Purification and separation of the diastereomers was accomplished by column chromatography on silica gel (EtOAc) to afford a low polarity diastereomer (78 mg, 24%) and a high polarity diastereomer (48 mg, 15%).
