Compd. (IV) react with acetyl chloride or acetyl bromide at 0-1000≦̸C, followed by the reaction of V to give I(R1=C1-4 alkyl; R2=C1-6 alkyl, Ph; R3=H, C1-6 alkyl, C2-6 alkenyl, benzyl, R4=alkyl, alkenyl, cycloalckyl, etc.; X=CH, N; n=0-1), which exhibited plant growth regulator. Thus, 17.6g 1, 1-dimethoxy-3,3-dimethyl-but-2-ylmethylether was treated triazole and treated with 12.3g acetyl bromide to give 7.4g 1-(1',2'4'-triazol- 1'-yl)-1-methoxy-3,3-dimethylbut-2-ylmethyl ether.
