Procedure
The title compound was obtained by an operation similar to that of Example 2 and using (2-mercapto-1,3-thiazol-4-yl)acetic acid ethyl ester synthesized in Example 1 and bromoacetic acid tert-butyl ester to give {2-[(2-tert-butoxy-2-oxoethyl)thio]-1,3-thiazol-4-yl}acetic acid ethyl ester, followed by sequential operations similar to those of Examples 3, 4 and 34.
