실험 절차

Diethyl N-(4-(N-(2-amino-4-hydroxy-6-quinazolinyl)methyl-N-(5-uracilyl)methyl-amino)benzoyl)-L-glutamate (0.327 g) was suspended in a mixture of water (7 ml) and ethanol (2 ml) and treated with 1N NaOH aq. (6 mol. eq.) Vigorous shaking gave a solution within 30 min. After a further 1.5 hr. the solution was clarified by filtration and the pH brought to 4.0 using 1N HCl aq. A particulate precipitate of the product resulted. It was freed from inorganic ions by three cycles of suspension-centrifugation-decantation. The amorphous white solid was dried at 40° C. in vacuo, to yield the pure diacid, N-(4-(N-(2-amino-4-hydroxy-6-quinazolinyl)methyl-N-(5-uracilyl)methyl-amino)benzoyl)-L-glutamic acid (CB 3743), as its dihydrate (68%), m.p. 250°-255° C. The structure was confirmed by elemental analysis (C,H,N) and by uv spectroscopy (spectrum determined in 0.1N NaOH aq.). λ(nm) (ε) maxima: 310 (29,200), 276.5(22,000), 230 (50,700); minima: 282.5 (21,500), 251.5 (11.600).
