Participants

Reaction Steps

Following the procedure as described in Example 8, making variations only as required to use N-benzyl-5-bromo-3-methylthiophene-2-carboxamide in place of N-benzyl-5-bromothiophene-3-carboxamide to react with 4-(benzyloxy)pyridin-2(1H)-one, the title compound was obtained as colorless solid in 49% yield: mp 153-154° C.; 1H NMR (300 MHz, CDCl3) δ 7.55 (d, J=7.9 Hz, 1H), 7.43-7.27 (m, 10H), 6.84 (s, 1H), 6.20-6.11 (m, 2H), 6.05 (d, J=2.7 Hz, 1H), 5.03 (s, 2H), 4.59 (d, J=5.7 Hz, 2H), 2.54 (s, 3H); 13C NMR (75 MHz, CDCl3) δ 166.4, 162.5, 161.9, 139.2, 137.6, 134.2, 128.43, 128.40, 128.3, 127.5, 127.4, 127.2, 126.7, 121.8, 102.9, 97.8, 70.3, 43.6, 15.6; MS (ES+) m/z 431.3 (M+1).
