A convenient method for the preparation of arylamines via nucleophilic displacement of methoxy- and/or fluorobenzoates with lithium amides is presented. Treatment of 2,6-di-tert-butyl-4-methoxyphenyl 2- or 4-fluorobenzoate (2 or 7) with lithium diarylamides 3e-h in THF and/or THF/HMPA under mild conditions affords the 2- or 4-(diarylamino)benzoates 4e-h or 8g, h in good to excellent yields.
