Diethylamine → N,N-diethyl-4-formylbenzamide

Participants

Reaction Steps

4-Formylbenzoic acid (11.2 g, 74.6 mmol) and triethylamine (10.4 mL, 75 mmol) was dissolved in THF (100 mL) and cooled to −10° C. i-Butylchloroformate (10.3 mL, 78 mmol) was added and stirring was continued for 10 minutes at −10° C. before diethylamine (9.7 mL, 94 mmol) was added and solution was allowed to reach 25° C. After concentration, aqueous workup and chromatography on silica (0-100% EtOAc in heptane), a total of 7.4 g (50%) compound I was obtained.
