Reaction Steps
A degassed mixture of tert-butyl 2-chloro-7,8-dihydro-5H-pyrido[2,3-b]azepine-9(6H)-carboxylate (690 mg, 2.44 mmol), potassium trifluoro(vinyl)borate (344 mg, 2.44 mmol), PdCl2(dppf). CH2Cl2 (199 mg, 0.244 mmol) and Cs2CO3 (2.00 g, 6.1 mmol) in THF (50 ml) and H2O (10 ml) was heated at 80° C. for 3.5 h. The reaction mixture was diluted with H2O and extracted with DCM (2×). The combined organic layers were dried over Na2SO4 and evaporated. The crude material was applied to a 120 g RediSep® silica column and purified by normal phase chromatography, eluting with 1:3 EtOAc/heptanes. Product-containing fractions were combined and evaporated to give the title compound as an off-white solid. (UPLC-MS 6) tR 1.18; ESI-MS 275.2 [M+H]+.
