実験手順

A mixture of 2-(3-chloropyridin-2-yl)-N-(2-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acetamide (0.192 g, 0.497 mmol) and CDI (0.322 g, 1.986 mmol) in toluene (2 mL) was heated at 110° C. After 5 h, the cooled mixture was diluted with EtOAc and washed sequentially with water and brine. The combined aqueous layers were extracted with EtOAc, and the combined organic phases were dried and concentrated. The residue was purified by column chromatography on silica gel, eluting with EtOAc-hexanes, to provide racemic 5-chloro-2-(2-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-1H-pyrido[1,2-c]pyrimidine-1,3(2H)-dione as a bright yellow solid (0.133 g, 65% yield). Mass spectrum m/z 413 (M+H)+. 1H NMR (400 MHz, chloroform-d) δ 8.26 (dt, J=7.6, 0.9 Hz, 1H), 7.94 (dd, J=7.5, 1.3 Hz, 1H), 7.36 (t, J=7.6 Hz, 1H), 7.27-7.18 (m, 2H), 6.36 (t, J=7.3 Hz, 1H), 6.31 (s, 1H), 1.57 (s, 3H), 1.36 (s, 12H).
