Tributylphosphine → HCID 58629891, compound

Participants

Reaction Steps

A stirred solution of 1-{6-[4-(trifluoromethyl)phenyl]-2-pyridinyl}-1-pentanol (62 mg, 0.20 mmol) and ethyl (2E)-3-(4-hydroxy-3,5-dimethylphenyl)-2-propenoate (79 mg, 0.36 mmol) in THF (4 mL) at 0° C. under nitrogen was added ADDP (101 mg, 0.40 mmol) followed by tri-N-butylphosphine (0.100 mL, 0.40 mmol). The resulting mixture was then allowed to warm slowly to ambient temperature overnight. After 66 h the solvent was removed under vacuum (Genevac) and the resulting solid partitioned between DCM (5 mL) and water (5 mL), the layers separated and the aqueous re-extracted with DCM (5 mL). The combined organic layer was then reduced under vacuum and purified by SPE (silica, 10 g cartridge) eluting with cyclohexane:EtOAc (gradient 20:1 to 1:1) to give the title compound (35 mg).
