実験手順

A solution of (E)-ethyl 3-(2-amino-4-(trans-4-methoxycyclohexylamino)-6-methylpyrimidin-5-yl)acrylate (674 mg, 2.02 mmol) thiophenol (621 ul, 6.05 mmol), 1,5-diazabicyclo5,4,0)undec-5-ene (1.81 mL, 12.1 mmol) and triethylamine (1.69 mL, 12.1 mmol) in N′,N-dimethylformamide (15 mL) was heated in the microwave for 30 minutes at 100° C. then in an oil bath at 100° C. overnight. The reaction mixture was diluted with methyltertbutylether and washed with saturated sodium carbonate, brine, 0.1 N hydrochloric acid, brine, dried (MgSO4), filtered and concentrated. The combined aqueous layer was extracted with dichloromethane (2×). The organic layer was dried (MgSO4), filtered and concentrated. The crude product was purified by flash chromatography eluting with chloroform/methanol (0-5%) to afford 2-amino-8-(trans-4-methoxycyclohexyl)-4-methylpyrido[2,3-d]pyrimidin-7(8H)-one (482 mg, 83%).
