Reaction Steps
The product of Example 46B (1.22 g) was dissolved in MeOH (8 mL) and treated with 50% NaOH (1.75 g, 21.27 mmol) and water (6 mL). The mixture was heated until all was soluble and stirred at 25° C. for 1 hr. The solvents were removed in vacuo, water (6 mL) was added and the solution acidified with HCl. The mixture was extracted with CHCl3, dried (Na2SO4), filtered and concentrated in vacuo. The residue was crystallized from ether and heptane (1:4) to yield the title compound (0.953 g), m.p. 114-116° C.
