Procedure
In dimethoxyethane, were mixed and stirred 0.35 g of 3-(2-bromoethoxy)-4-(2,6-dichlorophenyl)-1,2,5-thiadiazol e, 0.3 g methylpropylamine at 50° C. for 6 hours. The reaction mixture was concentrated, and was purified by silica gel chromatography to obtain 0.2 g of 3-(2,6-dichlorophenyl)-4-[2-(N-methyl-N-propylamino)ethoxy]-1,2,5-thiadiazole.
