실험 절차

A solution of methyl 2-chloro-4-methyl-6-(m-tolylamino)pyrimidine-5-carboxylate (1.2 g, 4.11 mmol), tert-butyl (1S,2R)-2-aminocyclohexylcarbamate (0.882 g, 4.11 mmol) and triethylamine (1.720 mL, 12.34 mmol) in DMA (10 mL) was heated at 90° C. for 4 h. The solution was then diluted with EtOAc, washed with brine and water. The organic extract was dried and concentrated under reduced pressure to give a light yellow residue; white crystals were formed upon triturating with ACN (5 mL). The resultant solid was filtered, washed with ACN, and dried to give the title compound as white solid (1.2 g, 62%). [M+H] calc'd for C25H35N5O4, 470; found, 470.
