The synthetic route is as follows., HPLC of Formula: C8H5F3O2
a) 4-Dimethylamino-2.6-difluoro-benzoic acid methyl ester (6a) To a stirred solution of 4,28 g (22.5 mmol) 2.4,6-Trifluoro-benzoic acid methyl ester (Apollo) and 60.0 ml dimethylsulphoxid are added 2.23 g (27.0 mmol) dimethylamine hydrochloride and 6.54 g (47.3 mmol) potassium carbonate. The reaction mixture is stirred for 5h at 55C in an autoclave and is reduced with high vacuum rotation evaporator at 65C. The residue is diluted with dichloromethane, washed twice with water. The combined water phases are extracted with dichloromethane. The combined dichloromethane phases are washed with diluted sodium hydrogen carbonate solution, dried with sodium sulphate and concentrated. The oily crude is purified by column chromatography and the desired product 6a is obtained in 74 % yield (3.59 g, 16.7 mmol). MS-ESI: 216 (M+ +1,69).
