Procedure

To a solution of compound 342 (540 mg, 0.864 mmol) in THF (12 ml) and water (6 ml) was added LiOH monohydrate (363 mg, 8.64 mmol). The mixture was stirred 48 h at room temperature and THF was removed under reduced pressure. The aqueous solution was diluted with water (10 ml) and acidified to pH 4 using 1N HCl. The suspension was filtered and the precipitate was dried under high vacuum to afford compound 343 (485 mg, 0.79 mmol, 92% yield) as a beige solid. MS (m/z): 611.5 (M+H).
