Reaction Steps

The compound of Step 3 of Example 9 (28.91 g) was suspended in ethanol (100 ml), and 4 N hydrochloric acid-dioxane (23.37 ml) was added at room temperature. After stirring at room temperature for two hours, the solvent was distilled off under reduced pressure, and the residue was recrystallized from ethanol/isopropyl ether (50 ml/150 ml). The resulting solid was collected by filtration, washed with isopropyl ether and then dried under reduced pressure to give 30.83 g of the title compound as a solid.
