Reaction Conditions:
with sodium hydroxide in ethanol;water at 40 - 100;
Steps:
5 Example 5
Compound V (40.2 g, 0.24 mmol), ethanol (200 mL),Water (200 mL), sodium hydroxide (29.2 g, 0.73 mol) was added, and the temperature was raised to 40-100 ° C until the reaction was completed. Concentrated ethanol, washed with methyl tert-butyl ether, lowered the temperature to 0 to 10 ° C, adjusted the pH to 3 to 4 with dilute hydrochloric acid, and filtered and dried to obtain a light brown solid.Compound VI (43.2 g, 96.4%).
