This example illustrates further methods according to the invention of preparing the compounds of formula I to the invention. In this example 1 g. of morpholine is added to a solution containing 0.3 g. of 1,2-epoxy-3-(5-4'-methylhexylaminocarbonylthiazol-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 the 1,2-epoxy-3-(5-aminocarbonylthiazol-2-oxy)-propane is essentially complete. The mixture is then evaporated to dryness yielding a crude residue of 1 -(N-morpholino-3-(5-4'-methylhexylaminocarbonylthiazol-2-oxy)-2-propanol which is then further purified by thin-layer chromatography on silica gel.
