Reaction Steps

This example illustrates further methods according to the invention of preparing further compounds of formula I of the invention. In this example 1 g. of β-(4-aminocarbonylphenoxy)-ethylamine (Cox et al, J. Med. Chem., v. 16, No. 11 (1973)) is added to a solution containing 0.4 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-(5-4'-methylhexylaminocarbonylthiazol-2-oxy)-propane is essentially complete. The mixture is then evaporated to dryness yielding a crude residue which is then further purified by thin-layer chromatography on silica gel yielding 1-[β-(4-aminocarbonylphenoxy)-ethylamino]-3-(5-4'-methylhexylaminocarbonylthiazol-2-oxy)-2-propanol.
