Versuchsvorschrift

To a solution of EXAMPLE 22A (1.9 g) in tetrahydrofuran (10 mL) and water (5 mL) was added lithium hydroxide (1 g) in water (5 mL). Methanol was added until homogeneous and the solution stirred at ambient temperature for 4 hours. The mixture was concentrated to 5 mL and the residue acidified to pH 2 with 2 N hydrochloric acid. Ethyl acetate and water were added and the organic phase separated, washed with water, dried over magnesium sulfate, filtered and concentrated to give the title compound (1.7 g, 95%). MS (DCI): m/z 227 (M+H)+.
