Procedure

To 3.3 g (15 mmol) of the product of Step B in 200 mL of 3:1 tetrahydrofuran/methanol was added 50 mL (50 mmol) of 1N aqueous lithium hydroxide solution and the resulting solution was stirred at ambient temperature for 16 h, then concentrated and acidified with 100 mL of 1N aqueous hydrochloric acid. The resulting mixture was extracted with three 100-mL portions of ethyl acetate, and the organic phases combined and washed sequentially with 1N hydrochloric acid and saturated aqueous brine (100 mL each). The organic phase was dried over magnesium sulfate, filtered, and evaporated in vacuo to yield the title compound as a colorless foamy solid that was used without further purification. LC/MS 382.4 (M+23).
