Reaction Steps
In analogy to the procedure described in example 78.4, 2-chloro-N-{2-[2-(3-chloro-phenyl)-ethoxy]-1-imino-ethyl}-5-ethyl-nicotinamide was treated with potassium carbonate in DMF for 5 h at 100° C. to obtain 2-[2-(3-chloro-phenyl)-ethoxymethyl]-6-ethyl-3H-pyrido[2,3-d]pyrimidin-4-one as off-white crystals. MS: m/e=344.3 [M+H+].
