Procedure
3.6 Grams of 3-(3-iodo-2-propynyloxy)-4-cyano-5-methylsulfonylisothiazole was dissolved in 30 ml of dimethoxyethane, 1.5 g of dimethylamine (as 50% aqueous solution) was added at room temperature with stirring, and then the reaction solution was stirred at 50° C. for 2 hours. Water was added to precipitate crystals, which were then collected by filtration, washed with water, dried and recrystallized from ethyl acetate. Thus, 2.2 g of white crystals having a melting point of 171° to 172° C. was obtained.
