실험 절차

A mixture of 1-((2-(dimethoxymethyl)-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)methyl)-4-methylpiperazin-2-one (intermediate 81, 268 mg, 0.641 mmol), phenyl(5-cyano-4-isopropoxypyridin-2-yl)carbamate (intermediate 96, 834 mg, 1.122 mmol) and DMAP (7.83 mg, 0.064 mmol) in acetonitrile (2.6 ml) was heated at reflux for 3.5 h. The reaction mixture was evaporated and applied to a 24 g RediSep silica column as a DCM solution and purified by normal phase chromatography, eluting with a gradient from DCM to 10% MeOH in DCM. Product containing fractions were combined and evaporated to give the title compound as an off-white solid. (UPLC-MS 6) tR 0.92; ESI-MS 538.7 [M+H]+.
