A novel naphthyridine derivative showing high activity as a tachykinin receptor antagonist can be produced at high efficiency by reacting an acylating agent such as a carboxylic acid derivative with a compound represented by the formula (1):
wherein R1, R, and R3 represent independently a hydrogen atom, a lower alkyl group, a lower alkoxyl group, an aryl group, a heteroaryl group, an amino group, etc., and X1 and X2 represent respectively a halogen atom.
一种作为速激肽受体拮抗剂具有高活性的新型萘啶衍生物可通过使酰化剂(如羧酸衍生物)与式(1)所代表的化合物反应而高效制得:
其中 R1、R 和 R3 分别代表氢原子、低级烷基、低级烷氧基、芳基、杂芳基、氨基等,X1 和 X2 分别代表卤素原子。
