실험 절차
0.084 g of citric acid is added at RT to a solution of 0.3 g of the compound obtained in EXAMPLE 1' in 5 ml of EtOH and 3 ml of DCM, and the mixture is left stirring for 2 hours at RT. It is concentrated under vacuum and the residue is recrystallized in 2-propanol. 0.26 g of the expected product is obtained, m.p.=168° C.
