실험 절차
The ester obtained in Step b (0.36 g; 1.45 mmol) is dissolved in 10 ml of 6N HCl. The reaction mixture is heated at 55° C. for 4 hours. The reaction mixture is then concentrated, and the residue is taken up in AcOEt. The resulting precipitate, corresponding to the title product, is suction-filtered off over a frit and isolated in the form of a pale yellow solid.
