NEW MATERIAL:An amide derivative shown by the formula I [Q is thienyl, furyl, or phenyl; A is group shown by the formula II(R<3> is H, lower alkyl, or lower alkoxycarbonyl), or group shown by the formula III(R<4> and R<5> are H, or lower alkyl; R<6> is H, lower alkyl, or lower alkoxycarbonyl); R<1> is H or lower alkyl; R<2> is H, lower alkyl, or phenyl; R<1> and R<2> are 1-5C alkylene may be linked to form ring; M is imidazole or triazole]. EXAMPLE:N-2-(3-Methylbuten-1-yl)-N-(1-imidazolylcarbonyl)-benzylamine. USE:A herbicide. Effective for weeds such as annual, perennial gramineous weeds, broad-leaved weeds, etc. in paddy fields and plowed fields. PREPARATION:A carbamoyl chloride intermediate shown by the formula IV is reacted with a compound shown by the formula V in the presence of a base, to give a compound shown by the formula I .
