Reaction Steps

This Example shows the preparation of exemplary compound Dye 9 and its physical properties. A mixture of 1.34 g (10 mmol) 2-methyl-oxazolo[4,5-b]pyridine and 2 ml ethyliodide in a closed system was kept 2 h at 110° C. The product was precipitated with acetone and filtered off. The yellow crystalline product was filtered off and washed with diethyl ether to provide 2.47 g (86%) 4-ethyl-2-methyl-oxazolo[4,5-b]pyridinium iodide, which was of sufficient purity to carry on to the next synthetic step.
