Reaction Steps
TEA (0.08 ml, 0.68 mmol, 1.2 eq) and methyl formyl reagent [259] (0.1 g, 0.56 mmol, 1.0 eq) was added to a solution of aspirin [4154] and 2-acetoxybenzoic acid, (0.1 g, 0.56 mmol, 1.0 eq) in DMF (2 ml). The reaction mixture was heated at 45° C. for 16 h, followed by cooling to room temperature and dilution with water. The organic material was extracted with ethyl acetate, was washed with water dried over Na2SO4 and evaporated under vacuum to get crude product. The crude product was purified by silica gel column chromatography (ethyl acetate in cyclohexane 100-200 mesh) to yield a dark colored sticky product [318], ((2-acetoxybenzoyl)oxy)methyl nicotinate, (0.09 g, 50%).
