Azacycloalkyl carbonyl cyclic amine compound

A compound of Formula (I) or a salt thereof,

• wherein:
• Ring A is 9-hydroxy-6-azaspiro [3.5]nonan-7-yl;
• Y is hydrogen, C1-4 alkyl, C3-6 cycloalkyl, a 6-membered aromatic hydrocarbon ring, a 5- or 6-membered non-aromatic heterocycle, or a 5- or 6-membered aromatic heterocycle;
• wherein the C1-4 alkyl may be substituted with 1 to 5 substituents independently selected from halogen, —OH, —O—(C1-4 alkyl), and amino;
• and wherein the C3-6 cycloalkyl, the 6-membered aromatic hydrocarbon ring, the 5- or 6-membered non-aromatic heterocycle, and the 5- or 6-membered aromatic heterocycle may be substituted with 1 to 3 substituents independently selected from halogen, —OH, —O—(C1-4 alkyl), oxo, amino, cyano, nitro, and C1-4 alkyl which may be substituted with 1 to 5 independently selected halogens;
• L is pyrazolyl, thiazolyl, 1,2,4-oxadiazolyl, 1,3,4-oxadiazolyl, 1,2,3-triazolyl, tetrazolyl, pyridyl, pyrimidinyl, (oxadiazolyl)-(C1-C2 alkylene), (tetrazolyl)-(C1-C2 alkylene), (oxadiazolyl)-C(═O)— or —C(═O)-pyrrolidinyl;
• Z is C3-6 cycloalkyl, a 6-membered aromatic hydrocarbon ring, a 4- to 6-membered non-aromatic heterocycle, a 5- or 6-membered aromatic heterocycle, or an optionally substituted —O—(C1-4 alkyl);
• wherein the C3-6 cycloalkyl, the 6-membered aromatic hydrocarbon ring, the 4- to 6-membered non-aromatic heterocycle, the 5- or 6-membered aromatic heterocycle, and the —O—(C1-4 alkyl) may be substituted with 1 to 3 substituents independently selected from halogen, —OH, —O—(C1-4 alkyl), oxo, amino, cyano, nitro, and C1-4 alkyl which may be substituted with 1 to 5 independently selected halogens;
• with the proviso that when L is (oxadiazolyl)-C(═O)—, Z is a 4- to 6-membered non-aromatic heterocycle having at least one nitrogen;
• wherein the 4- to 6-membered non-aromatic heterocycle having at least one nitrogen may be substituted with 1 to 3 substituents independently selected from halogen, —OH, —O—(C1-4 alkyl), oxo, amino, cyano, nitro, and C1-4 alkyl which may be substituted with 1 to 5 independently selected halogens;
• and
• m and n are each independently 1 or 2.
