実験手順
[(S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-morpholin-4-yl-4-oxobutyl]carbamic acid tert-butyl ester (172 mg, 0.338 mol) obtained in Step 1 above was dissolved in N,N-dimethylformamide (1.5 ml), and then piperidine (84 μl) was added thereto. After the solution was stirred at room temperature for 30 minutes, the solvent was concentrated under reduced pressure. The resulting crude product was purified by silica gel column chromatography (developing solvent: dichloromethane:methanol=20:1) to yield ((S)-3-amino-4-morpholin-4-yl-4-oxobutyl)carbamic acid tert-butyl ester (95 mg) as a colorless oily material.
