実験手順
A solution of 4-[[4-amino-4-(S)-(tetrahydro-pyran-4-yl)-butyryl]-(2-benzyloxy-ethyl)-amino]-cis-cyclohexanecarboxylic acid benzyl ester (1.9 g, 3.5 mmol) and 5-nitro-2-phenoxy-pyridine-4-carboxaldehyde (0.86 g, 3.53 mmol) in 1,2 dichloroethane (100 mL) was stirred at room temperature for 4 hours, and then NaBH(OAc)3 (1.4 g, 6.6 mmol) was added. The resulting mixture was stirred at room temperature overnight. Then 1N NaOH was added, and the reaction mixture was then poured into EtOAc (200 mL). The organic layer washed with aq. NaCl, dried with MgSO4, filtered, and evaporated to yield a residue. The residue was purified by column chromatography (1:1 heptane/EtOAc) to yield 4-{(2-benzyloxy-ethyl)-[4-[(5-nitro-2-phenoxy-pyridin-4-ylmethyl)-amino]-4-(S)-(tetrahydro-pyran-4-yl)-butyryl]-amino}-cis-cyclohexanecarboxylic acid benzyl ester as an oil.
