The product of step (f) (0.7316 g) suspended in water was treated with sodium bicarbonate (0.45 g) and stirred until complete dissolution occurred. The solution was treated with pure acetone and cooled. The precipitated product was collected by filtration and dried under reduced pressure at 80° C. for four hours, affording (0.38 g) of the title compound.
