Versuchsvorschrift

A mixture of 0.47 g (1.0 eq) of 4-[4-(2,4-diamino-6-hydroxypyrimidin-5-yl)butyl]benzoic acid, 0.62 g (1.5 eq) of phenyl N-phenylphosphoramidochloridate, 0.79 g (5.0 eq) of N-methylmorpholine, and 50 mL of anhydrous N-methylpyrrolidone is stirred under nitrogen at ambient temperatures for one hour. There is then added 0.75 g (2.0 eq) of diethyl L-glutamate hydrochloride and stirring is continued under nitrogen for 24 hours. The solvent is removed by vacuum distillation and chloroform was added to the residue. The chloroform solution is washed with water, dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residue is chromatographed with 1:9 methanol:chloroform to yield diethyl N-(4-[4-(2,4-diamino-6-hydroxypyrimidin-5-yl)butyl]benzoyl)-L-glutamate, m.p. 75°-76° C.; IR (KBr) vmax 3320, 2920, 2915, 1845, 1720, 1580, 1529, 1427, 1368, 1326, 1192, 1093, 1021, 849 and 750 cm-1 ; 1H NMR (CDCl3) delta 11.58 (bs, 1 H (3)--NH), 7.68 (d, J=7.9 Hz, 2H, Ar), 7.33 (d, J=7.9 Hz, 1H, NH), 7.17 (d, J=7.9 Hz, 2H, Ar), 5.54 (bs, 2H (2)--NH2), 4.76-4.82 (m, 1H, CH), 4.71 (bs, 2H, (6)--NH2), B 4.23 (q, J=7.11 Hz, 2H, CO2CH2), 4.12 (q, J=6.5 Hz, 2H, CO2CH2), 2.15-2.68 (m, 8H, 2° aliphatic) 1.57-1.66 (m, 2H, 2° aliphatic), 1.35-1.45 (m, 2H, 2° aliphatic), 1.30 (t, J=7.1 Hz, 3H, CH3), 1.22 (t, J=7.1 Hz, 3H, CH3); HRMS calcd for C24H33N5O6 (M+): 487.2430; found: 487.2415; other ions at m/e 348, 313, 285, 195, 167, 139, 97, and 84.
