4-(2-Chloroethyl)phenol → 4-{2-[4-(3-Trifluoromethylphenyl)-piperidinyl]ethyl}phenol

Participants

Reaction Steps

The procedure described in Example 1 was repeated except that 4-(3-trifluoromethylphenyl)piperidine (the product of Preparation L) and 2-(p-hydroxyphenyl)ethyl chloride were the respective starting materials employed, using the same molar porportions as before. In this particular case, the corresponding final product obtained 4-{2-[4-(3-trifluoromethylphenyl)-piperidinyl]ethyl}phenol (yield, 65%), which was also converted to the hydrochloride salt. The pure base product was characterized by means of nuclear magnetic resonance data: NMR (CDCl3) δ6.8-7.6 (m, 8H), 0.6-4.0 (m, 14H). The hydrochloride salt melted at 207°-210° C. and was further characterized by means of elemental analysis.
