3-(Trifluoromethyl)benzoic acid → HCID 67329761, compound

Participants

Reaction Steps

To a solution of [6-(5-Amino-2-methyl-phenyl)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-2-yl]-pyrimidin-5-yl-amine (50.0 mg, 0.15 mmol), 3-Trifluoromethylbenzoic acid (28.5 mg, 0.15 mmol), and DIPEA (78 μl, 0.45 mmol) in DMF was added HATU (59 mg, 0.15 mmol), and the reaction mixture was stirred for 3 hour at room temperature. The reaction mixture is 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 49.75 mg (65.6%) of N-{4-Methyl-3-[2-(pyrimidin-5-ylamino)-7,8-dihydro-5H-pyrido[4,3-d]pyrimidin-6-yl]-phenyl}-3-trifluoromethyl benzamide [17] as a pale yellow solid.
