Procedure

To a solution of EXAMPLE 387B (0.300 g) in tetrahydrofuran (5 mL) and methanol (1 mL) was added 1.0M lithium hydroxide (1.506 mL) and the suspension was heated to 55° C. After 3 hours, the reaction was cooled, diluted with dichloromethane (20 mL) and water (10 mL), and quenched with 1N aqueous HCl (1.5 mL). The organic layer was separated and the aqueous layer was extracted with 20 ml of dichloromethane. The combined organic extracts were washed with brine (25 mL), dried over magnesium sulfate, filtered, and concentrated to give the title compound.
