Reaction Steps

A mixture of 3-(2-chloro-5-methylpyrimidin-4-yl)-1-methyl-1H-indole (Intermediate 80, 350 mg, 1.36 mmol), 4-fluoro-2-methoxy-5-nitroaniline (Intermediate 23, 265 mg, 1.43 mmol) and p-toluenesulfonic acid (284 mg, 1.49 mmol) in 2-pentanol (25 mL) was heated at 125° C. for 24 h. The mixture was then cooled and concentrated in vacuo. The resulting gum was used without further purification; m/z: ES+ MH+ 240.13.
