Reaction Steps

This example illustrates further methods according to the invention of preparing the compounds of formula I of the invention. In this example 0.6 g. of ethanolamine is added to a solution of 0.3 g. of 1,2-epoxy-3-(thiazol-2-oxy)-propane in 20 ml. of anhydrous absolute ethanol at 20°C. The resulting mixture is monitored by thin-layer chromatographic analysis and allowed to stand until conversion of 1,2-epoxy-3-(thiazol-2-oxy)-propane is essentially complete. The mixture is then evaporated to dryness yielding a crude residue of 1-(β-hydroxyethylamino)-3-(thiazol-2-oxy)-2-propanol which is then further purified by thin-layer chromatography.
