Synthesis of Formamide Derivatives Catalyzed by Vitamin B1 Hydrochloride
N-Formination of aniline using VB1 as a catalyst:
A mixture of aniline (5 mmol), formic acid (1 mL), and VB1 (0.1 mmol, 2 mol%) is heated at 80 °C under stirring for 10 minutes. After completion of the reaction as indicated by TLC, 20 mL of EtOAc is added and washed with 5% HCl aq., 5% Na2CO3 aq., and brine. Then, the organic layer is dried over MgSO4 and concentrated to afford N-formylaniline in 96% yield without further purification.
