실험 절차

A solution of Intermediate 1 (1 g, 3.24 mmol) and 3-amino-4-methylbenzamide (584 mg, 3.89 mmol) in 0.08 M PTSA in 1,4-dioxane was heated to 90° C. for 48 h. TLC showed the completion of starting material (TLC system: 10% methanol/DCM, (Rf): 0.5). The reaction mixture was concentrated, quenched with water, and the precipitated solid was filtered and dried under vacuum. The crude solid was purified by silica gel column chromatography by using 3% methanol/DCM as eluents. The purified solid was further triturated with ether, filtered and dried under vacuum to get the title compound as an off-white solid (430 mg, 31%). 1HNMR (400 MHz, D6-DMSO) δ 2.17 (s, 3H), 5.78-5.81 (dd, 1H J=1.8, 10.1 Hz), 6.28-6.32 (dd, 1H J=1.8, 17 Hz), 6.43-6.50 (dd, 1H J=10.1, 17 Hz), 7.04-7.08 (m, 2H), 7.18-7.24 (m, 2H), 7.27 (br s, 1H), 7.52-7.54 (dd, 1H J=1.7, 7.9 Hz), 7.73-7.76 (m, 1H), 7.87 (br s, 1H), 7.92 (d, 1H), 8.03 (s, 1H), 8.39 (s, 1H), 8.62 (s, 1H), 10.19 (s, 1H). MS m/z: 423.5 (ES+, M+H).
