; and an alkylene chain of 1 to 4 carbon atoms in length between the moiety R
4
and the nitrogen atom. N, wherein (a) one or more of the 1 to 4 carbon atoms of the alkylene chain may optionally be substituted with one or two C
1-4
alkyl groups; and/or (b) one carbon atom of the 1 to 4 carbon atoms of the alkylene chain may optionally be replaced by a cyclopropane-1,1-diyl or 1,1-cyclobutanediyl group; and/or (c) one carbon atom of the 1 to 4 carbon atoms of the alkylene chain may optionally be replaced by C(═O), S(O), or SO
