実験手順

To a solution of 1-bromo-3-phenoxy-propan-2-ol (5) (248 mg., 1.07 mmol.) in toluene (2 mL.) was added 2-amino-1-benzylbenzimidazole (3) (200 mg., 0.90 mmol) and the mixture was heated at reflux overnight under N2 gas. The reaction mixture was cooled to room temperature and filtered. Crystallization of the collected solid from isopropanol gave 1 as white crystals (85 mg., 23%). Recrystallization of the mother liquor afforded additional 1 as white crystals (70 mg., 19%). 1H-NMR (DMSO-d6) δ 4.12 (s, 2H), 4.33 (s, 1H), 4.43 (s, 2H), 5.57 (s, 2H), 6.96 (m, 3H), 7.21-7.38 (m, 10H), 7.46 (d, J=8.0 Hz, 1H), 7.62 (d, J=7.6 Hz, 1H), 9.18 (s, 2H); 13C-NMR (DMSO-d6) δ 45.58, 46.10, 66.54, 69.43, 110.53, 111.11, 120.71, 123.39, 123.47, 127.11, 127.91, 128.72, 129.39, 129.45, 130.39, 134.56, 150.27, 157.67, 158.33.
