실험 절차

A solution of 1-chloro-4-(prop-2-ynyloxy)methylphthalazine (3) (20 mg, 0.09 mmol) and 5-amino-1-phenylbenzimidazole (15 mg, 0.07 mmol) in i-PrOH (2 mL) is stirred at 95° C. under argon for 2.5 h. The reaction mixture is concentrated, quenched with sat. NaHCO3 (10 mL), and extracted with CHCl3 (60 mL). The extract is washed (brine) and dried. After solvent removal at reduced pressure, the residue is purified on silica gel (0:1:2 to 1:25:0 methanol/ethyl acetate/hexane) to give 8 mg (27%) of BI-3035 as a light-brown solid, mp 89-91° C. IR 3321, 2927, 1496 cm−1; 1H NMR (CDCl3) δ 2.60 (t, J=2.4 Hz, 1H, CH≡C—CH2O), 4.98 (s, 2H, CH2), 5.36 (d, J=2.4 Hz, CH≡CCH2O), 6.94 (dd, J=8.7, 2.1 Hz, 1H, 6-BenzimidH), 7.27 (d, J=2.1 Hz, 1H, 4-BenzimidH), 7.41 (d, J=8.7 Hz, 1H, 7-BenzimidH), 7.41-7.63 (m, 5H, PhH), 7.90-8.02 (m, 2H, 6,7-PhthH), 8.06 (s, 1H, 2-BenzimidH), 8.14 (m, 1H, 5-PhthH), 8.35 (m, 1H, 8-PhthH).
