Participants

Reaction Steps

0.34 g of sodium hydroxide is added to 1.92 g (4.22 mmol) of the diester obtained in Example 14 in 25 ml of methanol and the mixture is kept under reflux for 24 hours. After the same treatment as in Example 8 and recrystallization from the isopropyl ether-ethyl acetate mixture, 1.7 g (91%) of the expected derivative are isolated, which derivative melts at 272°-273° C.
