실험 절차

Aniline (0.126 mL, 1.38 mmol) was added to a solution of 3-formyl-azepane-1-carboxylic acid benzyl ester (147) (0.300 g, 1.15 mmol) in 5% HOAc in MeOH (11.5 mL). The reaction was stirred for approx. 20 minutes, then NaBH3CN (0.2164 g, 3.44 mmol) was slowly added and the reaction was stirred at room temperature overnight. The reaction was then concentrated in vacuo and EtOAc and a few drops of 10% NaOH were added. The organic was washed with saturated NaCl (aq), dried with Na2SO4, concentrated in vacuo, to give crude 3-phenylaminomethyl-azepane-1-carboxylic acid benzyl ester (148). Compound 148 was used in the next step without further purification.
