An improved method for the N-formylation of secondary amines using chlorotrimethylsilane and imidazole in N,N-dimethylformamide is described. The reaction conditions are tolerant of ester functional groups, and an amine hydrochloride may be N-formylated using a slight modification of the procedure.
