Reaction Steps

Prepared by the same method as described in example 1 except that (i) 4-iodoaniline was used in place of 4-bromoaniline in step 2 and (ii) (R)-[4-(2-azetidin-1-yl-2-oxo-ethoxy)-phenyl]-tert-butoxycarbonylamino-acetic acid was used in place of (R)-tert-butyloxycarbonylamino-4-methoxyphenylglycine. (R)-[4-(2-Azetidin-1-yl-2-oxo-ethoxy)-phenyl]-tert-butoxycarbonylamino-acetic acid was prepared by a method similar to that used for the preparation of (R)-tert-butyloxycarbonylamino-4-methoxyphenylglycine in example 1 except that 1-azetidin-1-yl-2-chloro-ethanone was used in place of iodomethane.
