Participants

Reaction Steps

84 g of methyl 2-allyloxy-4-acetaminobenzoate and 84 g of N-methylpyrrolidone were introduced into a 500 ml round-bottomed flask. The contents were heated quickly to reflux which was then maintained for 30 minutes, and the solution was then cooled slightly and poured into water. Crystallation was immediate. The same operations were repeated with the same quantities of methyl 2-allyloxy-4-acetaminobenzoate and N-methylpyrrolidone and the products from the two trials were combined and cooled, drained, washed with water and dried at 50° C.
