Versuchsvorschrift

To a solution of the product from Step A (48.8 g, 109 mmol) in 1L of methanol was added 1M sodium hydroxide solution (325 mL, 325 mmol). Over the course of four days, additional methanol (3 L) and sodium hydroxide solution (325 mL, 325 mmol) were added. The solution was concentrated in vacuo, and partitioned between EtOAc and water. The organic layer was washed with brine, dried (Na2SO4), filtered, and concentrated in vacuo to provide the titled product.
