(Wyrick S D, Booth R G, Myers A M, Owens C E, Kula N S, Baldessarini R J, McPhail A T, and Mailman R B (1993) Synthesis and pharmacological evaluation of 1-phenyl-3-amino-1,2,3,4-tetrahydronaphthalenes as ligands for a novel receptor with sigma-like neuromodulatory activity. J Med Chem 36:2542-2551) (2R,4R)-4-Cyclohexyl-1,2,3,4-tetrahydronaphthalen-2-ol 2a (0.23 g, 0.1 mol), p-toluenesulfonyl chloride (0.20 g, 0.11 mol), and pyridine (1.5 mL) was stirred in solution for 24 hours at rt, under inert atmosphere (N2). The solvent was removed and the crude material was purified by column chromatography (Si-gel) to give 3a in a 62% yield. HRMS m/z Calcd for C23H28O3S 407.1651 [M+Na]+. Found 407.1631.
