PROCEDURE

实验过程

A solution of LiOH.H2O (35 mg, 0.87 mmol, 4-6 (176 mg, 0.29 mmol), and 20% aq. THF (10 mL) was stirred at ambient temperature for 1 h. The reaction mixture was acidified with 1M NaHSO4 and extracted with EtOAc (3×). The combined extracts were dried (MgSO4) and concentrated to give 4-7 (171 mg) as a foam. Rf 0.73 (silica, 9:0.5:0.5 CH2Cl2 /CH3OH/AcOH). ##STR49## 3-[4-(Piperidin-4-yl)butyloxy]isoxazole-5-carbonyl-2(S)-phenylsulfonylamino-β-alanine (4-8)
