mine substituted at the 4'-phenyl position have been prepared and evaluated in vitro for serotonin transporter (SERT) selectivity. Several derivatives were prepared where the 4'-position was either unsubstituted 13 and 33a or substituted with methyl 14a and 33b, ethenyl 14b and 34, ethyl 16 and 35, hydroxymethyl 20 and 41, hydroxyethyl 22, fluoroethyl 23, hydroxypropyl 27, and fluoropropyl 28.
