Reaction Steps
A mixture of example 1130C (355 mg, 0.84 mmol) and sodium hydroxide (1 mL of a 4N aqueous solution, 4 mmol) in 4 mnL of ethanol was heated to reflux for 6 hours and then cooled to room temperature. The mixture was diluted with water and the pH adjusted to 5 with aqueuos phosphoric acid. The mixture was extracted with 3 portions of ethyl acetate and the combined organic fractions were washed with water and brine, dried, filtered and concentrated to provide 270 mg (78%) of the title compound. MS (ESI+): 410 (MH+).
