실험 절차

To a solution of 4-((1R,3R,4R)-3-hydroxy-4-methylcyclohexylamino)-2-(methylsulfonyl)pyrimidine-5-carbonitrile (446 mg, 1.437 mmol; synthesis described herein) in NMP (5 mL) was added bicyclo[1.1.1]pentan-1-amine hydrochloride (258 mg, 2.155 mmol; prepared according to Org. Lett., 13(17): 4746-4748 (2011)) and DIEA (1.255 mL, 7.18 mmol). The reaction was stirred at 80° C. for 4 h and then allowed to cool to ambient temperature. The solvent was evaporated under reduced pressure and the residue was purified by flash chromatography (0-90% ethyl acetate in hexanes) to afford 2-(bicyclo[1.1.1]pentan-1-ylamino)-4-((1R,3R,4R)-3-hydroxy-4-methylcyclohexylamino)pyrimidine-5-carbonitrile (381 mg, 1.216 mmol, 85% yield). MS (ESI): m/z 314.0 [M+1]+.
