実験手順
To anhydrous dichloromethane (170 ml) are added 2,4,5-trifluoro-3-methylaniline (16.89 g) and dimethyl sulfide (11 ml). Thereto N-chlorosuccinimide (17.2 g) is added gradually below 5° C. After stirring for 30 minutes, triethylamine (21 ml) is added dropwise and the mixture is refluxed over night. After the mixture is cooled and made alkaline with 5% aqueous sodium hydroxide solution, the resultant is extracted with dichloromethane, and the extract is washed with water and dried. The solvent is distilled off under reduced pressure and the residue is purified by silica-gel column-chromatography (dichloromethane: n-hexane =1:1) to give 2,4,5-trifluoro-3-methyl-6-methylthiomethylaniline (8.3 g).
