As a result, both Example 1 and Example 4, in which the benzamide moiety and the 2-position of the nitrogen-containing heterocycle are linked via a two-carbon (ethylene group) ', showed significant dose-dependent contraction-enhancing effects. Was. On the other hand, the compound described in U.S. Pat. No. 4,772,459 and Reference Example 14 bonded through one carbon (methylene group) had a weak effect. In addition, Reference Example 15 which binds via 3 carbons (propylene group) did not show any action.
