Participants

Reaction Steps

The title compound was synthesized from N-methylamine (6 mL of 33 w % solution in EtOH) and the compound of Example 216 (1.04 g) by the same procedure used for Example 207 except that 1 mL of DMA was added. The reaction was carried out at 82° C. for 5 days. The title compound, isolated by preparative HPLC, is a white solid (0.29 g, 52%), M.p. 269–270° C. (decomposition). Its structure was confirmed by 1H NMR and LC/MS: 1H NMR (d6-DMSO): δ 2.76 (d, 3H, J=5.5 Hz), 2.84–3.99 (m, 4H), 6.16 (s, 2H), 6.57 (d, 1H, J=9 Hz), 6.91–7.04 (m, 3H), 7.12 (d, 1H, J=1 Hz), 7.22–7.34 (m, 3H), 7.46–7.54 (m, 3H), 10.19 (s, 1H). ESI mass spectrum for C26H22ClN6O4+: 517 (M+1).
