実験手順

A mixture of 275 mg of 2,6-dichloro-4-phenylquinazoline (compound No. II-2) and 486 mg of furfurylamine was stirred at 85° C. for 40 minutes and then poured into 50 ml of water. The mixture was extracted with ethyl acetate, and the resultant extract was washed with water and then concentrated. The resulting residue was recrystallized from ethanol to obtain 280 mg of the titled compound. Mp.142.0° C. 1H NMR (CDCl3): 4.77 (2H, d, J=5.6 Hz), 5.70 (1H, br. t, J=5.6 Hz), 6.29-6.32 (2H, m), 7.36 (1H, dd, J=1.8, 0.9 Hz), 7.53-7.70 (7H, m), 7.78 (1H, d, J=2.2 Hz).
