実験手順
In analogy to the procedure described in example 78.4, 5-butyl-2-chloro-N-{2-[2-(3-chloro-phenyl)-ethoxy]-1-imino-ethyl}-nicotinamide was treated with KOtBu in DMSO to obtain 6-butyl-2-[2-(3-chloro-phenyl)-ethoxymethyl]-3H-pyrido[2,3-d]pyrimidin-4-one as off-white crystals. MS: m/e=370.4 [M−H−].
