Reaction Steps

To one of the above aliquots of crude 2-(chlorocarbonyl)-2,5,7,8-tetramethylchroman-6-yl acetate in 10 mL CH2Cl2 was added 1.0 mL diisopropylethylamine followed by 315 mg 1-hexylamine and overnight stirring. The reaction mixture was poured into 1.0 M citric acid and 50 mL EtOAc added. The organic layer was separated and purified by flash chromatography to give 781 mg of 2-(hexylcarbamoyl)-2,5,7,8-tetramethylchroman-6-yl acetate, as a clear syrup. MS (m/z): M+376.3
