    A series of structurally constrained derivatives of the potent H 3 inverse agonist 1 was designed, synthesized, and evaluated as histamine H 3 receptor inverse agonists. As a result, the N-cyclobutylpiperidin-4-yloxy group as in 2f was identified as an optimal surrogate structure for the flexible 1-pyrrolidinopropoxy group of 1. Subsequent optimization of the quinazolinone core of 2f revealed that
