Document Type and Number:
Japanese Patent JPH08225515
Kind Code:
A
Abstract:

PURPOSE: To obtain an N-substituted phenylcarbamic acid derivative having ultrahigh controlling effects on disease injuries such as blast of rice plants and useful as an agricultural and horticultural germicide by reacting specific compounds.

CONSTITUTION: This compound of formula I [R1 is H, a (halo)1-6C alkyl, a 1-6C alkoxy-1-6C alkyl, etc.; R2 is H, a (halo)1-6C alkylcyano-1-6C alkyl, etc.; R3 is a (halo)1-6C alkyl; R4 and R5 are each H, cyano, a (halo)1-6C alkyl, a (halo)3-6C cycloalkyl, etc.; Y is O], e.g. methyl-N-ethoxy-N-[2-[1-[N'-{1-(3- chlorophenyl)ethylidene}-hydrazono]-ethyloxymethyl]phenyl] carbamate. Furthermore, the objective compound is preferably obtained by reacting a compound of formula II (Z is a halogen) with a compound of formula III in the presence of a base (e.g. sodium carbonate) or a silver compound (e.g. silver oxide) in an inert solvent such as isopropanol under conditions of 40°C to ambient temperature and 30min to 48hr, etc.
