Reaction Steps

To a solution of example 7 (0.26 g, 0.53 mmol) and methanol (10 mL) is added 50% aqueous LiOH aqueous (10 mL). The mixture is stirred at room temperature overnight. Solvent is removed. The residue is dissolved in water and acidified with 3N HCl to pH about 7 and extracted with ethyl acetate. The ethyl acetate layer is concentrated to afford the title compound (0.25 g, 98%) as a yellow solid.
