실험 절차

A mixture of 2-chloro-6-hydroxyquinolin-5-carbaldehyde (3) (104 mg, 0.5 mmol), 4-(4-methylpiperazine-1-carbonyl)phenylboronic acid (4) (198 mg, 0.7 mmol) and K2CO3 (174 mg, 1.25 mmol) in a mixture of i-PrOH and water (6 mL 10:1) was purged with Argon for five minutes in a microwave vessel. A tablet of PdOAc2(Sphos)4 (Aldrich, Cat. No. 694088) was added under an Argon atmosphere then the vessel was sealed and irradiated for 45 min at 165° C. Upon cooling, the reaction mixture was filtered through a silica plug using MeOH. The solution was evaporated and purified by Flash chromatography using 0-5% MeOH in CH2Cl2. The product was recrystallized from CH2Cl2/hexanes to afford the title compound. MS (ESI): 376 (M+H)+. 1H NMR (δ, DMSO (2.5 ppm)): 10.74 (s, 1H), 9.44 8.25, 7.21 and 7.49 (4d, 4×1H), 8.29 and 7.54 (2d, 2×2H), 3.64, 3.38, 2.41 and 2.33 (4 broad s, 4×2H), 2.23 (s, 3H).
