Procedure

A mixture of sodium thiosulfate (49.6 g, 0.2 m), sodium iodide (1 g), N-(2-chloroethyl)-2,2,4,7-tetramethyl-1,2,3,4-tetrahydroquinoline (25.2 g, 0.1 m), water (100 ml), and ethanol (100 ml) was refluxed fro 3 hrs. The mixture was cooled and extracted with 2-75 ml portions of toluene. The aqueous layer then contained essentially pure product and aliquots were used to prepare dyes without further purification.
