Reaction Conditions
Operation in experiment
With triethylamine;
Example 65 4-(3,4-Methylenedioxybenzyl)amino-6-cyanoquinazoline STR126 15 ml of isopropyl alcohol, 75 mg of triethylamine and 125 mg of piperonylamine were added to 140 mg of <strong>[150449-97-1]4-chloro-6-cyanoquinazoline</strong>. The obtained mixture was heated under reflux for 5 hours and filtered to recover a precipitate. This precipitate was introduced to a silica gel column, followed by eluding with ethyl acetate to give 200 mg of the title compound. molecular formula; C17 H12 N4 O2 yield (%); 89 m.p. (C.); 243~244 Mass; 305 (M+1)+ NMR delta (DMSO-d6); 4.67 (2H, d, J=5.6Hz), 5.96 (2H, s), 6.84 (2H, s), 6.95 (1H, s), 7.77 (1H, d, J=8.4Hz), 8.56 (1H, s), 8.89 (1H, s), 9.04 (1H, br)
