Potassium Cyanide → HCID 57942747, compound

Participants

Reaction Steps

To 3-(1,1,2,2-tetrafluoroethoxy)benzaldehyde (222 mg, 1.0 mmol) in ethyl acetate (5 mL) was added a solution of KCN (195 mg, 3.0 mmol) and NaHSO3 (312 mg, 3.0 mmol) dissolved in H2O (10 mL). The reaction was stirred at rt for 8 h. Another portion of KCN (195 mg, 3.0 mmol) and NaHSO3 (312 mg, 3.0 mmol) dissolved in H2O (10 mL) was added. It was left stirring overnight before it was extracted with ethyl acetate (2×50 mL). The combined organic extracts were dried and concentrated to give 130A as an oil. It was used for next step without purification. 1H NMR (400 MHz, CDCl3) δ ppm 5.57 (s, 1H) 5.78-6.04 (m, 1H) 7.28 (d, J=6.15 Hz, 1H) 7.39 (s, 1H) 7.43-7.52 (m, 2H). 19F NMR (376 MHz, CDCl3) δ ppm −136.72, −88.04.
