Reaction Steps

20 ml of 20% aqueous potassium hydroxide solution are added to the solution of 1 g of 2-bromolysergic acid methyl ester in 6 ml of ethanol, then the solution is stirred in a bath of 80° C. for one hour. The pH value of the solution cooled down is adjusted to 7 by adding aqueous hydrochloric acid. The crystalline precipitate obtained on cooling is filtered off, washed with water and dried to give the title compound in a yield of 0.5 g (0.0014 mole, 50%).
