Procedure
The title compound was prepared from Intermediate 3 and 3-[(tetrazol-5-yl)amino]aniline using a similar method to that described for Example 4, except that anhydrous acetonitrile was used as the reaction solvent; the crude product was purified by flash chromatography (silica gel, dichloromethane-methanol, 93:7 to 80:20) and recrystallized from methanol; mp 190°-193° C.; [α]D25 +8.4° (c=0.50, dimethylformamide); the spectroscopic properties (1H-NMR and MS spectra) of this material were identical to those described for its racemate (Example 2). (Found: C, 59.78; H, 5.98; N, 25.68.C24H27N9O2 ×0.6H2O requires: C, 59.52; H, 5.87; N, 26.03%).
