(2Rs,5rs)-4-[5-(4-fluoro-phenyl)-1-(toluene-4-sulfonyl)-pyrrolidin-2-yl]-n-butyramidine → (2Rs,5rs)-2-{3-[5-(4-fluoro-phenyl)-1-(toluene-4-sulfonyl)-pyrrolidin-2-yl]-propyl}-4,6-dimethyl-pyrimidine

Participants

Reaction Steps

A stirred solution of (2RS,5RS)-4-[5-(4-fluoro-phenyl)-1-(toluene-4-sulfonyl)-pyrrolidin-2-yl]-N-butyramidine (0.35 g, 0.87 mmol) in pentan-2,4-dione (7 ml) was heated for 3 h at 125° C. Evaporation and purification by column chromatography on silica gel (ethyl acetate) yielded the title compound (0.15 g, 38%) as a light yellow oil, MS: m/e=468.3 (M+H+).
