Potassium Cyanide → HCID 58691835, compound

Participants

Reaction Steps

To a solution of 2,4-dibromo-3-(bromomethyl)thiophene (1.00 g, 3.00 mmol) in EtOH (10 mL) was added a solution of potassium cyanide (0.29 g, 4.5 mmol) in H2O (0.5 mL). The mixture was heated to reflux overnight. The solvent was removed and the residue was partitioned between EtOAc and H2O. The EtOAc was dried (MgSO4) and the solvent removed. The residue was recrystalized from EtOH to yield (2,4-dibromothien-3-yl)acetonitrile (0.72 g, 86%). mp 75.5-77° C.; 1H NMR (500 MHz, DMSO-d6) δ: 3.94 (s, 2H), 7.94 (s, 1H). MS (EI) m/z 279/281/283 (M+.). Anal. Calcd for C6H3Br2NS: C, 25.65; H, 1.08; N, 4.99. Found: C, 26.04; H, 1.18; N, 4.86.
