Procedure
Using an analogous procedure as described in example 21.1, (RS)-(3-amino-2-oxo-2H-pyridin-1-yl)-ethoxy-acetic acid ethyl ester (example 19.2) was reacted with 3-methoxy phenylboronic acid to give (RS)-ethoxy-[3-(3-methoxy-phenylamino)-2-oxo-2H-pyridin-1-yl]-acetic acid ethyl ester. Light green gum. MS 347.4 ([M+H]+)
