Procedure
A solution of 1-tert-butyldimethylsilyl-4(S)-(3-methyl-5-isoxazolyl)-2-azetidinone (0.9 g) in EtOH (10 ml) was added HCl (16.9 mmol)/EtOH (4.2 ml) at room temperature at 0° C. The reaction mixture was stirred at room temperature for 2 hours, then evaporated in vacuo. The residue was recrystallized from diethyl ether to give 3(S)-(3-methyl-5-isoxazolyl)-β-alanine ethyl ester hydrochloride (0.67 g) as a white solid.
