NEW MATERIAL:A compound shown by the formula I (X is halogen; Y is lower alkoxy, or lower alkoxymethyl). EXAMPLE:2-Chloro-4-amino-6-methoxymethylphenol. USE:An intermediate for synthesizing an active ingredient for agricultural and horticultural fungicide. A compound shown by the formula I is reacted with isopropyl chloroformate, and with cyanomethyl chloride to give an isopropyl 3-halo- 4-cyanomethoxy-5-substituted phenylcarbamate shown by the formula II having strong fungicidal action on plants fungi showing resistance to benzimidazole and thiaphanate fungicides. PREPARATION:A 2-halo-4-nitro-6-substituted phenol shown by the formula III is reduced to give a compound shown by the formula I . The reduction is carried out by reduction with sodium hydroxide, reduction with iron powder, or catalytic reduction, etc.
