실험 절차
The ester product of Example 1 (0.70 g, 2.4 mmole) was dissolved in 15 ml of methanol and 1 ml of 2N NaOH and heated to reflux for 21/2 hours. The mixture was maintained at room temperature overnight. Methanol was evaporated, and the residue partitioned between about 30 ml of toluene and about 30 ml of aqueous HCl. The toluene extract was dried over sodium sulfate and evaporated to give 0.35 g (66.8%) of product as a yellow solid which was identical with an authentic sample. This target product was further identified by NMR.
