Participants

Reaction Steps

2-(4-Methyl-piperazin-1-yl)-1-phenyl-ethanol (38) (2.0 g, 9.09 mmol) was dissolved in 50 mL of THF. 4-trifluoromethyl phenol was added to the solution and then triphenylphosphine. After complete dissolution, the mixture was cooled to 0° C. and after 10 minutes DIAD was added dropwise. Ice-bath was removed and the reaction mixture was stirred at room temperature for 48 hours. The product was purified using flash chromatography, using pure ethyl acetate. The product 14a (2.78 g, 7.64 mmol, 84%) was afforded as a yellow oil. H-NMR (CDCl3): δ 7.39 (2H, d, J=8.62), 7.36 (5H, m), 6.91 (2H, d, J=8.58), 5.38 (1H, dd, J=3.11, 3.10 Hz), 3.03 (1H, dd, J=8.39, 8.38), 2.71 (1H, dd, J=3.14, 3.14), 2.63 (4H, b), 2.44 (4H, b), 2.27 (3H, s).
