실험 절차

4.4 g (0.01841 mol) of the dihydrochloride obtained in stage (c) above are dissolved in 50 ml of water. 2.2 g of sodium hydroxide pellets and 3 ml of acetone are added. The mixture is left to stand overnight at room temperature (15°-20° C.) and extracted with 3×100 ml of CHCl3, and the chloroform phase is washed with 30 ml of water, dried over MgSO4 and then filtered to remove MgSO4. The filtrate is evaporated to dryness; recrystallization from petroleum ether (fraction boiling at 45°-60° C.) gives 2.6 g (yield: 68.5%) of CRL 41 365. M.p.=108° C.
