Reaction Steps
A room temperature solution of Example 1A (10.0 g, 43.4 mmol) and saturated LiOH (50 mL) in THF (100 mL) was stirred for 16 hours, slowly adjusted to pH 2-4 with 6M HCl, diluted with ethyl acetate (200 mL), washed with water (100 mL) and brine (50 mL), dried (MgSO4), filtered, and concentrated to provide the desired product of sufficient purity for subsequent use. MS (ESI(−)) m/e 215 (M−H)−.
