実験手順
A mixture of 2-(4,5-dihydro-1H-imidazol-2-yl)-4,5-dimethoxyaniline (0.15 g, 0.68 mmol) and methyl-3-oxo-3(3-pyridinyl)propanoate (0.20 g, 1.12 mmol) was stirred at 155. for 1 hour. The reaction mixture was purified by column chromatography on silica-gel (dichloromethane/methanol, 25/1) to give (Z)-2-(8,9-dimethoxy-2,3-dihydroimidazo[1,2-c]quinazolin-5-yl)-1-(3-pyridinyl)ethenol (66.9 mg, 28%) as a yellow solid.
