実験手順

To a solution of [6-(5-Amino-2-methyl-phenyl)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-2-yl]-(4-chloro-phenyl)amine (54.87 mg, 0.15 mmol), 3-Trifluoromethylbenzoic acid (28.51 mg, 0.15 mmol), and Diisipropylethylamine (DIPEA) (78 μl, 0.45 mmol) in DMF (7.5 ml) was added 2-(7-Aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) (59 mg, 0.15 mmol) and the reaction mixture is stirred for 3 hour at room temperature. The reaction mixture was diluted with ethyl acetate and washed with 5% aqueous sodium bisulphate solution, saturated aqueous sodium bicarbonate solution and brine. The organic layer is dried over sodium sulphate and concentrated under reduced pressure. The crude product obtained was purified by column chromatography (SiO2, 2-10% methanol in chloroform to give of N-{3-[2-(4-chlorophenylamino)-7,8-dihydro-5H-pyrido[4,3-d]pyrimidin-6-yl]-4-methyl-phenyl}-3-trifluoromethylbenzamide [13] as a pale yellow solid. [Yield: 60.6 mg, 75.2%]
