Trichloroacetonitrile → HCID 86672614, compound

Participants

Reaction Steps

1,8-Diazabicyclo[5.4.0]undec-7-ene (1.00 ml, 6.83 mmol) was added to a dichloromethane (22 ml) solution of the compound (6.83 mmol) obtained in Step 2 above combined with trichloroacetonitrile (0.82 ml, 8.20 mmol) under ice cooling and the resulting mixture was stirred at room temperature for 1 hour. The solvent in the reaction mixture was evaporated under reduced pressure and the residue was dissolved in chloroform and added dropwise into n-hexane:ethyl acetate [4:1 (v/v)] mixed solvent. The resulting insoluble matter was removed by filtration through celite and the solvent in the filtrate was evaporated under reduced pressure. The residue obtained was purified by silica gel column chromatography [n-hexane:ethyl acetate=99:1→10:1 (v/v)] to give 2.1 g (77%) of the title compound as a colorless oil.
