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 for 3 hrs. The mixture was cooled and extracted with two 75 ml portions of toluene. The aqueous layer then containing essentially pure product and aliquots were used to prepare dyes without further purification.
