Procedure

β-Alanine (20 mmol) was reacted with valeryl chloride (22 mmol) in the presence of NaOH (40 mmol) in a mixture of H2 0 and ether using the method described in Example 5. The crude crystalline product (2.75 g, 79%) was recrystallized from a mixture of isopropyl ether (150 ml) and ethyl acetate (10 ml) to give title acid (1.51 g, 44%), m.p. 73°-76° C.
