    • NEW MATERIAL:A compound of formula I [R
      1 is H, alkyl, carboxy, alkoxycarbonyl, formula II (R
      4 is H or alkyl; R
      5 is alkyl, carboxyalkyl, etc.), formyl, phenyl, etc.; R
      2 is H, alkyl, alkoxycarbonyl or halogen; R
      1 and R
      2 together with the carbon atoms to which they are linked form a condensed benzene ring; R
      3 is H or alkyl; X is H or I ].
      EXAMPLE: 2-(N-Methyl-2-propynylamino)-5-methylthiazole.
      USE: With powerful antifungal action and low toxicity, and capable of exhibiting a germicidal or fungistatic effect not only on fungi infecting humans and cattle therewith but also on pathogenic germs of agricultural and forestry and horticultural crops.
      PROCESS: A 2-aminothiazole derivative of formula III is reacted with a 2-propynyl halide in an inert solvent in the presence of a base to afford the compound of formula I (X is H).
