실험 절차

A mixture of 1-(2-aminopyrimidin-4-yl)-6-bromo-N-(2-methoxyethyl)-1H-1,3-benzodiazol-2-amine (150 mg, 0.37 mmol), 2-(4-methyl-1,3-thiazol-2-yl)but-3-yn-2-ol (137.6 mg, 0.82 mmol), bis(triphenylphosphine)palladium(II) dichloride (150 mg, 0.21 mmol) and triethylamine (0.7 mL) in dimethylsulfoxide (1 mL) under nitrogen in a 10-mL sealed tube was stirred for 1 hr at 70° C. The reaction mixture was cooled to room temperature then purified on a silica gel column (dichloromethane/methanol, 8:1) to give 19.6 mg (11%) of 4-[1-(2-aminopyrimidin-4-yl)-2-[(2-methoxyethyl)amino]-1H-1,3-benzodiazol-6-yl]-2-(4-methyl-1,3-thiazol-2-yl)but-3-yn-2-ol as yellow oil: 1H NMR (300 MHz, DMSO) delta 8.40 (d, J=5.4 Hz, 2H), 8.22 (t, J=5.0 Hz 1H), 7.49 (s, 1H), 7.27 (d, J=8.1 Hz, 1H), 7.16 (t, J=10.5 Hz, 2H), 6.91 (d, J=5.4 Hz, 1H), 6.89 (s, 1H), 6.86 (s, 1H), 3.62-3.59 (m, 4H), 3.32 (d, J=12.3 Hz, 3H), 2.35 (s, 3H), 1.85 (s, 3H); LC-MS: m/z=+450 (M+H)+.
