Reaction Steps

To a suspension of the product of Example 52B in 1:1 THF:methanol (6 mL) was added 0.5 N aqueous lithium hydroxide (6 mL). The mixture was stirred at room temperature for 2 hours, adjusted to pH 3 with 1.0 N HCl, and filtered. The filter cake was washed with water and dried to give the title compound (0.133 g, 86%).
