6-Chloronaphth-2-ylsulphonyl chloride (2.61 g) was added in one portion to a stirred mixture of sodium sulphite heptahydrate (4.71 g), sodium bicarbonate (1.64 g) and water (25 ml) which had been heated to 70° C. The resultant mixture was heated to that temperature for 3 hours and then allowed to cool slowly to ambient temperature. The crystalline precipitate was isolated giving sodium 6-chloronaphth-2-ylsulphinate (2.4 g) which was used without further purification.
