Reaction Steps
The reaction of alpha-tocopherol with 4-aminobenzoic acid chloride was carried out in the same manner with Example I, except that 10 mol % of 4-(dimethylamino)pyridine was added together with pyridine. This reaction was confirmed to proceed in a similar pattern to that of Example I as measured by thin layer chromatography. The remaining processes of Example I were repeated to produce alpha-tocopherol 4-aminobenzoate (0.61 g, yield 68%).
