Reaction Steps

In one experiment, (Benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (41.73 g, 94.35 mmol) and triethylamine (88 mL, 630 mmol) were added to a mixture of (R)-2-(1-hydroxycyclohexyl)-2-(3-(trifluoromethoxy)phenyl)acetic acid (20.0 g, 62.9 mmol) and cis-2,6-dimethylpiperazine (7.17 g, 62.9 mmol) in methylene chloride (150 mL) at RT. After stirring for 18 h, the mixture was concentrated in vacuo. The residue was purified by flash chromatography on silica gel (50 to 100% ethyl acetate in heptane) to afford 1-(3,5-Dimethyl-piperazin-1-yl)-2-(R)-(1-hydroxy-cyclohexyl)-2-(3-trifluoromethoxy-phenyl)-ethanone (24.3 g, 93%).
