Reaction Steps

The title compound was synthesized using the method described for the compound of Example 104, replacing 1-chlorocarbonyl-2-imidazolidinone for by 4-methyl-1-piperazinecarbonyl chloride. After evaporation, the crude was purified by means of automated flash chromatography (SP01®TM-Biotage; gradient EtOAc-MeOH from 95:5 to 8:2) to afford a yellowish solid. Yield: 51.3%.
