Participants

Reaction Steps

A 2 mol/L aqueous sodium hydroxide solution (10 mL, equivalent to 20 mmol of sodium hydroxide) was added to an ethanol (30 mL) solution of the compound obtained in Example 36 (2.0 g, 5.3 mmol), and the mixture was stirred at room temperature for 2 hours. The solvents were distilled off, water was then added to the residue, and the mixture was adjusted to a pH of 7 with a diluted hydrochloric acid. The precipitated crystals were separated by filtration and dried, to give 1.1 g (59%) of the captioned compound.
