Fungicidal title compds. (I; Ar = Ph, naphtyl, substituted-Ph, naphtyl; R1 = hydroxymethyl, C1-6 alkoxymethyl, alkyl thiomethyl, substituted thiomethyl, phenoxy thiomethyl; R2=H, Cl, Br, C1-6 alkyl, substituted Ph; Y = O, S) were prepd. by acylation of II. Thus, 10 g α-Br-γ-butyrolactone, 6.68 g 2,6-dimethylaniline and 5.58 g dimethylpyridine were reacted at 85-90≦̸C, 12 hr to give 3-(N-dimethylphenylamino)-γ-butyrothiolactone, which was refluxed with 1.52 g chloroacetylchloride in 10 ml to give 2.5 g I(Ar = 2,6-dimethylphenyl; R1=Cl; R2 = Br, Y = S).
