Reaction Steps

2277 g of 66% hydrobromic acid and 308 g of methyl 2-hydroxy-3-allyl-4-acetaminobenzoate were introduced into a 3-liter round-bottomed flask equipped with a leakproof stirrer, a thermometer and a safety tube containing mercury so that a pressure of approximately 2 cm of mercury is created in the apparatus. The mixture was stirred for 4 hours and then allowed to stand overnight. 5 liters of water were then added. The precipitate formed was drained, washed with water and dried at 50° C.
