Reaction Conditions:
in ethanol;water;isopropyl alcohol at 20; for 4 h;
Steps:
4.1; 12.1
[Synthesis of the compound (28)]; The compound (27) (10.0 g, 0.042 mol) and sodium hydroxide (1.67 g, 0.042 mol) were subjected to stirring in a mixed solvent of ethanol (30 mL)/2-propanol (10 mL) at room temperature for 4 hours. After completion of the reaction, the solvent was removed under reduced pressure, and 2-propanol (100 mL) was added for washing twice to give the compound (28) (4.2 g, yield; 39%). Property data: IR (cm-1): 3206, 1205.; [Synthesis of the compound (28)]; The compound (27) (10.0 g, 0.042 mol) and sodium hydroxide (1.67 g, 0.042 mol) were subjected to stirring in a mixed solvent of ethanol (30 mL)/2-propanol (100 mL) at room temperature for 4 hours.
