Reaction Steps

6-Chloro-2-ethylimidazo[1,2-b]pyridazin-3-ylsulfonamide (1.50 g, 5.75 mmol) was suspended in methanol (30.0 ml) and stirred at room temperature, during which sodium methoxide (28%, 3.34 g, 17.3 mmol) was added thereto. The mixture was heated for 5 hours under reflux, and then the reaction solution was poured into ice-water (200 ml) and adjusted to pH 2 with conc. hydrochloric acid. The precipitated crystals were filtered and washed with water, to give the title compound as colorless crystals. The yield was 1.02 g (69.3%).
