The present invention provides a method of treatment of a subject suffering from a disease, such as schizophrenia, for which the administration of an NK-3 antagonist is indicated which comprises administering to that subject a therapeutically effective amount of a compound of formula I:
wherein, generally,
Q is
R
1
is benzyl, phenyl, thiophene or imidazolyl optionally substituted with C
1-4
alkyl or halogen, such as methyl, fluorine or bromine;
R
2
is hydrogen or C
1-4
alkyl such as methyl;
R
3
is phenyl;
R
4
is hydrogen;
R
5
is hydrogen or C
1-6
alkylcarbonyl such as methylcarbonyl;
X is —SO
2
— or —C(O)N(R
2
)SO
2
— where R
2
is preferably hydrogen;
Y is a bond, CH
2
or Z
1
where Z
1
is —N(R
f
)— in which R
f
is C
1-6
alkylcarbonyl such as ethylcarbonyl; and
R
6
is phenyl, pyrazolyl, pyridyl, pyrimidinyl or benzimidazolonyl optionally substituted with one or two groups chosen from C
1-6
alkyl and benzyl, such as methyl, ethyl and benzyl; or a pharmaceutically acceptable salt thereof.
