Procedure

The ester from (a) was dissolved in 10 mL of 4 N HCl in 1,4-dioxane at 0° C. for 1 hour. The solution was concentrated in vacuo and the salt neutralized by sodium bicarbonate solution and the product extracted with CH2Cl2. After concentration of the organic extract, the crude product was purified by reverse-phase HPLC to yield the desired product; MS, m/z 462=M+1.
