Abstract:
A method for producing a compound represented by the formula: ##STR14##or a salt thereof, wherein R.sup.1 represents an optionally substituted hydrocarbon group; R.sup.2 represents a hydrogen atom or an optionally substituted hydrocarbon group; and Q represents an optionally substituted heterocyclic group, which comprises:subjecting a compound represented by the formula: ##STR15##or a salt thereof, wherein R.sup.1 has the same meaning as defined above, to a nitration reaction (a), to obtain a mixture containing a compound represented by the formula: ##STR16##or a salt thereof, wherein R.sup.1 has the same meaning as defined above, andfurther subjecting the mixture without isolating or purifying the compound represented by the formula [II] or salt thereof to a reaction (b) with a compound represented by the formula:Q--CH.sub.2 --NH--R.sup.2 [III]or a salt thereof, wherein Q and R.sup.2 have the same meaning as defined above, to obtain the compound represented by the formula [IV].
