実験手順

The ester from above (1.05 g, 2.73 mmol) was dissolved in 20 mL of methanol with 8 mL of 1M potassium hydroxide and stirred overnight at room temperature. The methanol was removed in vacuo and the remaining aqueous solution was extracted with two 15 mL portions of ether. The aqueous layer was adjusted to a pH of 7 with 1M hydrochloric acid. The solution was chilled and the white powdery precipitate was collected by filtration to give 504 mg (46%) of (E)-3-(4-chloro-α-(4-methyl-1-piperazinyl)benzyl)cinnamic acid, m.p. 131°-141°. Calc. for C21H23ClN2O2.2H2O: C, 61.99; H, 6.69; N, 6.88; Cl, 8.71. Found: C, 61.98; H, 6.72; N, 6.89; Cl, 8.66.
