実験手順
6-(1H-Imidazol-1-yl)-2-phenylquinazoline, 50 mg (0.18 mmol), is suspended in 4 mL of acetonitrile, the mixture is then heated at reflux and 30 mg of L-tartaric acid are added, the suspension is heated at reflux for a further 30 min, it is filtered and then cooled to 0° C., and the resulting suspension is stirred at 25° C. for three days and then filtered and dried at 20° C., 20 mmHg, for 12 hours. 30 mg of product are obtained in the form of yellow crystals, KF=14.67%, Calculated for C17H12N4.C4H6O6.4H2O: C, 51.01; H, 5.30; N, 11.33. found: C, 50.64; H, 5.41; N, 11.28. XRPD form B. Form B heated at 40° C., 85% RH for 7 days is stable (XRPD), but gives rise to the amorphous form when heated at 90° C. for 12 hours.
