実験手順

A solution of the product of Step B (1.0 g) and 2-amino-4-picoline (0.357 g) in ethanol (4 mL) was heated at 73° C. for 18 hours. The reaction mixture was cooled to ambient temperature and the solvent evaporated in vacuo. A portion of the residue was purified via silica gel chromatography (ethyl acetate/hexane) directly. The remainder of the residue was dissolved in methanol/dichloromethane and treated with Dowex® 550A basic resin (Aldrich, Milwaukee, Wis.) for 10 minutes. The resin was removed via filtration and the filtrate evaporated prior to silica gel chromatography (ethyl acetate/hexane). The combined material (0.42 g) containing the title compound was used without further purification.
