Reaktionsschritte
To a solution of the product from Example 1A (1.0 g, 3.05 mmol) in anhydrous THF (30 ml) at 0° C. was added sodium borohydride (0.357 g, 9.44 mmol). The resulting mixture was stirred at 50° C. overnight. The cooled mixture was poured into water, extracted with ethyl acetate, dried over Na2SO4, filtered and concentrated in vacuo. The resulting solid was triturated with dichloromethane to give a tan solid that was collected by filtration and dried to give the title compound (0.82 gm, 81% yield).
