0.63 g (1.86 mmol) of 2-chloro-4-{[3-(1-chlorocyclopropyl)-1,2,4-thiadiazol-5-yl]oxy}-5-methylaniline is dissolved in 5 ml of toluene and treated with 0.50 g (3.71 mmol) of N-ethyl-N-methylformamide dimethyl acetal. The reaction mixture is refluxed for 12 h, subsequently cooled, freed from solvent under vacuum and purified by column chromatography. 0.62 g of product is obtained (82.0% purity, 71.3% yield; log P (pH 2.3)=1.62).
