The downstream synthesis method of this compound is introduced below.
To a 100 ml flask were added methyl 2,4-dichloro-6-methylpyrimidine-5-carboxylate (309 mg, 1.4 mmol), 1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazole-4-amine (234 mg, 1.4 mmol), 10 ml of acetonitrile and DIPEA (0.54 g, 4.18 mmol). The reaction mixture was stirred at 40 C. for 1 h, acetonitrile was evaporated under reduced pressure and then 30 ml of EtOAc was added. The mixture was washed with 60 ml of water and 30 ml of brine. The organic phase was dired and concentrated to give 405 mg of intermediate 7a as a grey solid. MS m/z (ESI): 352.1[M+H]+.
