Patent ID: 7915261

Claim:
A pyridyl non-aromatic nitrogen-containing heterocyclic-1-carboxylate compound of a general formula (IV) or its pharmaceutically acceptable salt: wherein the symbols in formula (IV) have the following meanings: ring A 1 represents benzene ring, piperidine ring or piperazine ring; L 1 represents lower alkylene, lower alkenylene, —N(R 15 )—C(═O)—, or —O—, wherein R 15 represents H, or lower alkyl; R 19 represents (i) a group selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; (ii) nitrogen-containing heteroaryl optionally substituted with the same or different 1 to 5 groups selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; (iii) R 16 —(lower alkylene)-O—; or (iv) R 17 R 18 N—C(═O)—, wherein R 16 represents (i) aryl optionally substituted with the same or different 1 to 5 groups selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; (ii) nitrogen-containing heteroaryl optionally substituted with the same or different 1 to 5 groups selected from the group consisting of H, halo, —CN, —CF 3 , lower alkyl, and —O-lower alkyl; or (iii) 3- to 8-membered cycloalkyl, wherein R 17 and R 18 are the same or different, each representing H or lower alkyl, or R 17 and R 18 may form, together with the N atom bonding thereto, 5- or 6-membered nitrogen-containing hetero ring, and R 20 represents —CONH 2 .
