Procedure

The product of step 11B is dissolved in tetrahydrofuran/methanol (1:1) and treated with excess 3N aqueous lithium hydroxide. The reaction is followed by HPLC for disappearance of starting material. The reaction is concentrated, diluted with additional water, and purified by passage down an-acidic ion exchange column. The product fractions are lyophilized to afford the product as a solid.
