Procedure
According to general procedure C, (RS)-[4-(6-amino-pyridin-3-yl)-2,6-difluoro-phenyl]-ethoxy-acetic acid (intermediate from example 334.4, contains 2 equivalent of NaCl) was reacted with 4-aminomethyl-3,5-difluoro-benzonitrile hydrochloride (example 318.1) to give (RS)-2-[4-(6-amino-pyridin-3-yl)-2,6-difluoro-phenyl]-N-(4-cyano-2,6-difluoro-benzyl)-2-ethoxy-acetamide as off-white solid.
