반응 단계
A solution of methyl 2-[3-fluoro-6-(methyloxy)-1,5-naphthyridin-4-yl]-2-propenoate (953 mg, 3.63 mmol), cis-phenylmethyl[3-fluoro-4-piperidinyl]carbamate Enantiomer 2 (for a synthesis see WO2004058144, prepared by analogy to Examples 142(b), (c) and (d) from the Enantiomer 2 of Example 142(a)) (1.1 g, 4.35 mmol) and 1,1,3,3-tetramethylguanidine (6 drops) in DMF (3.5 ml) was heated at 80° C. under argon for 3 hours, cooled and evaporated. Chromatography, eluting with 1% methanol/dichloromethane, gave the product in 100% yield.
