Lithium hydroxide monohydrate (7 mg) was added to a solution of N-tert-butoxycarbonyl-4-[2-(tert-butoxycarbonylamino)ethyl]-L-proline methyl ester (E, 50 mg) in tetrahydrofuran (0.5 mL)-methanol (0.5 mL)-water (0.5 mL). After stirring at room temperature for 4 hr, the reaction mixture was acidified with 10% citric acid and extracted with chloroform. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and evaporated in vacuo to give the title compound (52 mg).
