Procedure
Magnetic microcapsules 31 were obtained in the same manner as in Example 25 except that the purified enzyme solution (1) in Example 25 was replaced by the crude enzyme solution (3) and (R)-3-hydroxybutyryl CoA was replaced by (R,S)-3-hydroxy-5-phenoxyvaleryl CoA (prepared by hydrolyzing 3-hydroxy-5-phenoxy valerate obtained through a Reformatsky reaction with zinc using 3-phenoxypropanal and ethyl bromoacetate as raw materials, which were synthesized according to a procedure described in J. Org. Chem., 55, 1490-1492, 1990, to produce 3-hydroxy-5-phenoxy valeric acid and then following a procedure described in Eur. J. Biochem., 250, 432-439, 1997). The drug content in the microcapsules is shown in Table 5
