실험 절차

By following the procedure of Example 2(a) but using as starting material in Example 2(a) an appropriate starting material of formula II, for example, those described in Examples 2 to 14 and an appropriate aminoketone of formula III in which R2 and n are as described above and A is CH2NR4R5 wherein R4 and R5 are as described above, the amino compounds of formula I listed in Examples 31 to 46 are obtained. For example, according to the present procedure 2-phenyl-4-(β-hydroxyethyl)thiazole condenses with 1-(N,N-dimethylamino)-3-butanone to give the title compound, identical to the amine described in Example 31.
