Reaction Conditions

Reaction Steps

Aqueous sodium hydroxide (0.5 M, 1.1 mL) was added to a stirred solution of the product from Example 23.2 (22 mg, 0.046 mmol) in methanol (5 mL). The mixture was stirred at 50° C. for 24 h. Then aqueous hydrochloric acid (1.0 M) was added dropwise to adjust pH to 3˜4. The methanol was evaporated under reduced pressure and the resulting solid was collected by filtration and dried in vacuo to afford the desired compound as a brown solid (13 mg, 81%).
