Reaction Steps
Compound 185 (0.19 g) obtained in Example 185 was suspended in ethanol (1 ml), mixed with a 24% aqueous sodium hydroxide solution (1.3 ml), and heat-refluxed for 2 hours. The resultant was allowed to stand for cooling, mixed with water, and adjusted to PH 2 by adding 2N hydrochloric acid water. The precipitated solid was collected by filtration to give Compound 186(0.14 g, 80%) as colorless crystals.
