実験手順

To an ethanolic suspension of 4-trifluoromethyl-benzimidic acid ethyl ester hydrochloride salt (761 mg, 3.0 mmol, 1.5 eq.) was added sodium methoxide (162 mg, 3 mmol) in ethanol (20 ml.) and the resulting mixture stirred for 30 min.at r.t. 3-dimethylaminomethyl-benzoic acid hydrazide (386 mg, 2.0 mmol) in ethanol was then added at 20° C., followed by heating to reflux for 16 hrs. Upon cooling, the product mixture was filtered, solvent was evaporated and the residue subjected to preparative reversed-phase HPLC purification using a YMC ODS-AQ column (20×50 mm) and a (0.1% trifluoroacetic acid) water-acetonitrile gradient (25 ml/min. flow rate). The pure fractions were concentrated and the product obtained was converted to the hydrochloride salt in ether by addition of excess 5N HCl/iPrOH solution (1 ml) followed by solvent evaporation and high vacuum drying to afford the title compound (79 mg, 0.21 mmol, 10% yield) as a white foam. MS: m/e=347.4 (M+H+).
