Reaction Steps

A solution of methyl 3-amino-4-hydroxybenzoate (5.00 g, 29.9 mmol), isobutyryl chloride (3.51 g, 32.9 mmol), triethylamine (3.33 g, 32.9 mmol), pyridinium p-toluenesulfonate (2.5 g, 10 mmol) and xylene (100 mL) was heated to reflux overnight and then cooled to room temperature. The reaction was diluted with ethyl acetate (100 mL) and washed with water (2×50 mL), dried with magnesium sulfate, filtered and concentrated to give the title compound (6.82 g, quantitative yield) as a brown oil. Also prepared by this method were:
