실험 절차

A mixture of 6-bromo-3,4-dihydro-1H-1,8-naphthyridin-2-one (0.096 g, 0.42 mmole), from Preparation 3, and N-methyl-N-(3-methyl-1H-inden-2-ylmethyl)acrylamide (0.141 g, 0.62 mmole) in propionitrile (10 mL) was treated with (i-Pr)2NEt (0.15 mL, 0.08 mmole), palladium acetate (0.014 g, 0.062 mmole), and (o-tolyl)3P (0.025 g, 0.08 mmole), and the resulting mixture was heated at gentle reflux. After 18 hr, the reaction was cooled, filtered through celite®, and concentrated. Flash chromatography on silica gel (2% MeOH/CH2Cl2) gave the title compound (0.06 g, 41%) as a glassy solid: MS (ES) m/e 374.2 (M+H)+. Anal. Calcd for C23H23N3O2.1.25 H2O: C, 69.76; H, 6.41; N, 10.61. Found: C, 69.86; H, 6.67; N, 10.51.
