Reaction Steps
In analogy to the procedure described in example 78.3, 2-chloro-5-ethyl-nicotinic acid (example 124.1) was reacted with 2-[2-(3-chloro-4-fluoro-phenyl)-ethoxy]-acetamidine hydrochloride (example 82.2) in the presence of TBTU and DIPEA to give 2-chloro-N-{2-[2-(3-chloro-4-fluoro-phenyl)-ethoxy]-1-imino-ethyl}-5-ethyl-nicotinamide as yellow oil. MS: m/e=398.1 [M+H+].
