The present invention provides a novel compound having few side effects such as bradycardia and the like and having superior peripheral blood lymphocyte-decreasing effect.
The present invention provides a 2-aminobutanol compound represented by the following formula (I)
wherein R
1
is a hydrogen atom or P(═O) (OH)
2
, R
2
is an alkyl having 1 to 4 carbon atoms optionally substituted by hydroxyl group(s) or optionally substituted by halogen atom(s), R
3
is a hydrogen atom; a halogen atom; cyano; an alkyl having 1 to 4 carbon atoms optionally substituted by halogen atom(s); or an acyl having 2 to 5 carbon atoms optionally substituted by halogen atom(s), X is an oxygen atom, a sulfur atom, carbonyl or NR
4
wherein R
4
is a hydrogen atom or an alkyl having 1 to 4 carbon atoms, Ar
1
is an optionally substituted arylene or an optionally substituted heteroarylene, and Ar
2
is an optionally substituted aryl or an optionally substituted heteroaryl, provided that when X is an oxygen atom, Ar
1
is phenylene and Ar
2
is phenyl, then the phenyl for Ar
2
should be substituted, or a pharmaceutically acceptable acid addition salt thereof, or a hydrate thereof, or a solvate thereof, as well as a production method of the above-mentioned 2-aminobutanol compound.
