p-Toluenesulfonic acid monohydrate → HCID 59210411, compound

Participants

Reaction Steps

3-Iodo-N-(1,1-dimethyl-2-methylsulfanyl-ethyl)-phthalamic acid (0.39 g) and N-(3-dimethylaminopropyl)-N1-ethylcarbonyl diimidazole hydrochloride (0.19 g) were stirred in dichloromethane (10 ml) at room temperature for 30 minutes. Then, 2-methyl-4-[1-(3-trifluoromethyl-1H-pyrazol-1-yl)-ethyl]-aniline (0.30 g) and p-toluenesulphonic acid monohydrate (0.02 g) were added thereto and the mixture was stirred at room temperature for 3 hours. After distilling off the solvent under reduced pressure, the obtained residue was purified by silica gel column chromatography to obtain N2-(1,1-dimethyl-2-methylsulfanyl-ethyl)-3-iodo-N1-{2-methyl-4-[1-(3-trifluoromethyl-1H-pyrazol-1-yl)-ethyl]-phenyl}-phthalamide (0.38 g) (compound No. 558). mp. 79-86° C.
