    • 2, 10 HEPES, pH 7.5) containing agonists or antagonists. Electrodes are filled with 3 M KCl. Holding potential (Vh) = -60 or -90 mV. Currents induced by the application of drugs were digitized by a Data Translation a/d board and analyzed with axodata software. All test compounds were tested at 32 μM and are compared to a test dose of nicotine at 50 μM. Data is reported as a % nicotine response with the nicotine response defined as 100%.

    • The chloroformate used to prepare 7z was prepared in three-steps from 2-bromo-5-hydroxybenzaldehyde (Harmata, M.; Kahraman, M. J. Org. Chem. 1999, 64, 4949). 2-Bromo-5-hydroxybenzaldehyde was reacted with phenyl magnesium bromide in THF at rt to give 4-bromo-3-(hydroxy(phenyl)methyl)phenol in 88% yield. Swern oxidation provided (2-bromo-5-hydroxyphenyl)-(phenyl)methanone in 22% yield which was treated with phosgene to give the desired chloroformate.
