Procedure
The intended compound (2-b) was prepared in a yield of 75% by a method similar to the process A in EXAMPLE 2, except that ethyl (3R)-5-tert-butoxycarbonylamino-3-hydroxypentanoate (2-a), obtained by the above process B, was used instead of ethyl (3R)-5-benzyloxycarbonylamino-3-hydroxypentanoate (2-a).
