실험 절차

Following the procedure of Example 1, condensation of 1,4-dibromo-2,3-butanedione with 1,2-diamino-4-chlorobenzene yielded 2,3-bis(bromomethyl)-6-chloroquinoxaline, m.p. 149°-150° C.; 1H NMR (CDCl3, 400 MHz): δ4.89 and 4.90 (singlets, 4H, CH2), 7.74 (dd, J1 =8.9 Hz, J2 =2.3 Hz, 1H, H-7), 8.01 (d, J=8.9 Hz, 1H, H-8), 8.07 (d, J=2.3 Hz, 1H, H-5).
