실험 절차
(R)-2-tert-Butoxycarbonylamino-5-(4-tert-butoxy-phenyl)-pentanoic acid ethyl ester (179 g, 460 mmol) is dissolved in 7M NH3 in MeOH (400 ml, 2800 mmol) and stirred at room temperature for 4 days. The reaction is concentrated in vacuo keeping the temperature below 30° C. to afford [(R)-4-(4-tert-Butoxy-phenyl)-1-carbamoyl-butyl]-carbamic acid tert-butyl ester [M+H]+ 364
