The present invention relates to novel quinazoline derivatives with less skin irritation and an excellent action of strongly suppressing scratching behavior, and pharmaceutical compositions containing a quinazoline derivative as an active ingredient. The present invention is directed to the quinazoline derivatives represented by the general formula [1] or pharmaceutically acceptable salts thereof. In the general formula [1], R
1
represents hydrogen or the like; R
2
represents hydrogen or the like; R
3
and R
4
are the same or different and represent hydrogen, alkyl, alkoxy or halogen; R
5
is combined with R
6
to represent alkylene or represents hydrogen, hydroxy, alkyl, phenyl or alkoxy; R
