実験手順
10 g of 2-chloropyridine-3-sulfonamide (obtained in Stage A of Preparation 6) are dissolved in 100 cm3 of 40% aqueous methylamine solution and the solution is introduced into a sealed tube. The tube is placed at 150° C. for 18 hours. After cooling, the reaction mixture is concentrated under vacuum (rotary evaporator) to a volume of 30 cm3. The crystalline precipitate corresponding to the title compound is collected on a filter, washed with water and dried.
