実験手順

To a solution of 4-(3-chloro-4-methoxybenzylamino)-5-methoxycarbonyl-6-chloro-2-(4-hydroxypiperidin-1-yl)pyrimidine (prepared in the above (3)) 56 mg in N,N-dimethylacetamide 0.5 ml are added a solution of 5,6,7,8-tetrahydroimidazo[1,2-a]pyrazine 31 mg in N,N-dimethylacetamide 0.5 ml and triethylamine 27 μl at room temperature, and the mixture is stirred at 80-90° C. for 5 hours. The reaction mixture is diluted with an aqueous citric acid solution, made basic with an aqueous sodium hydrogen carbonate solution and extracted with ethyl acetate. The organic layer is washed, dried and concentrated in vacuo to give 4-(3-chloro-4-methoxybenzylamino)-5-methoxycarbonyl-6-(5,6,7,8-tetrahydroimidazo[1,2-a]pyrazin-7-yl)-2-(4-hydroxypiperidin-1-yl)pyrimidine as a pale yellow powder, 66 mg.
