Reaction Steps

73 g of potassium hydroxide were dissolved in 84 ml of water in a 2-liter round-bottomed flask and 387 ml of absolute ethanol and 130.5 g of 5-mercapto-2-methyl-2,3-dihydrobenzofuran-7-carboxylic acid were then added. 86 g of cyclopropylmethyl bromide were then quickly poured in and the contents were heated under reflux for 1 hour. After adding water, the contents were filtered and the solution was acidified by adding concentrated hydrochloric acid until a color change of Congo red was observed. The precipitate formed was drained, washed with water and dried at 40° C.
