実験手順

1.50 g (6.04 mmol) of the product from example 54A are heated overnight in a mixture of 75 ml of dioxane and 75 ml of 4-molar hydrochloric acid. The mixture is then alkalized with sodium carbonate solution. The precipitate is filtered off with suction, washed with water and dried. This affords 1.43 g (96% of theory) of the desired compound.
