실험 절차

A suspension of 7-bromo-4-(4-methoxy-benzyl)-1,3,4,5-tetrahydro-pyrido[2,3-e][1,4]diazepin-2-one (5.00 g, 13.8 mmol) in propionitrile (80 mL) and DMF (20 mL) was de-oxygenated with Ar for 25 min. The mixture was treated with tert-butyl acrylate (8.1 mL, 55 mmol) and (i-Pr)2EtN (5.1 mL, 29 mmol) and was de-oxygenated with Ar for 15 min. Pd(OAc)2 (0.32 g, 1.43 mmol) and P(o-tol)3 (0.85 g, 2.79 mmol) were added simultaneously, and the mixture was de-oxygenated a third time for 5 min. The mixture was heated to reflux overnight, then allowed to cool. The resulting precipitate was isolated by filtration. Purification by flash column chromatography (silica gel, CH2Cl2/MeOH, 99:1) gave the title compound (3.54 g, 63%) as a white solid: MS (ESI) m/e 410 (M+H)+.
