ethers for both compounds as their free bases in chloroform-d revealed that the 2-methyl homologue probably exists as a rapidly equilibrating mixture of conformers; it seems likely that it can adopt the active conformation proposed to be required by the dopamine receptor. The lack of activity is therefore attributed to the stericeffect of the 2-methyl group, consistent with explanations offered by
