[PROBLEMS] To provide a compound which can be used for the treatment of a disease associated with a calcium-sensing receptor (CaSR), particularly hyperparathyroidism. [MEANS FOR SOLVING PROBLEMS] It is found that a novel pyrrolidine derivative having an aminomethyl group substituted by an arylaklyl group or the like or a salt thereof has an excellent CaSR agonistic modulation effect and also has an excellent selectivity in the inhibition of CYP2D6 which may cause a drug-drug interaction. Thus, the novel pyrrolidine derivative is useful as a therapeutic agent for a disease associated with CaSR (e.g., hyperparathyroidism, renal osteodystrophy and hypercalcemia). ® KIPO & WIPO 2008 |
