실험 절차

A suspension of 7-bromo-3,3-dimethyl-1,3,4,5-tetrahydro-pyrido[2,3-e][1,4]diazepin-2-one (0.17 g, 0.63 mmol) in propionitrile (4 mL) and DMF (1 mL) was de-oxygenated with Ar for 10 min. The mixture was treated with N-methyl-N-(3-methyl-benzo[b]thiophen-2-ylmethyl)acrylamide (0.20 g, 0.81 mmol) and (i-Pr)2EtN (0.24 mL, 1.3 mmol) and was de-oxygenated with Ar for 5 min. Pd(OAc)2 (14 mg, 0.062 mmol) and P(o-tol)3 (38 mg, 0.12 mmol) were added simultaneously, and the mixture was de-oxygenated a third time for 5 min. The mixture was heated to reflux for 4 h, then allowed to cool. The resulting precipitate was isolated by filtration, washed with EtOAc, dissolved in CH2Cl2, and the solvent was removed in vacuo. Purification by flash column chromatography (silica gel, CH2Cl2/MeOH, 98:2) gave the title compound (0.15 g, 56%) as a white solid: 1H NMR (300 MHz, CDCl3) δ 8.97 (s, 1H), 8.45 (s, 1H), 7.77-7.65 (m, 3H), 7.53 (s, 1H), 7.40-7.29 (m, 2H), 6.98-6.84 (m, 1H), 4.94-4.89 (m, 2H), 4.02 (s, 2H), 3.15-3.10 (m, 3H), 2.43 (s, 3H), 1.70 (s, 1H), 1.49 (s, 6H); MS (ESI) m/e 435 (M+H)+.
