Reaction Steps
The mixture of 4,6-dichloro-2-(methylthio)pyrimidine (450 mg, 2.31 mmol), DIEA (894 mg, 6.92 mmol) and 2-oxa-5-azabicyclo[2.2.1]heptane (328 mg, 2.42 mmol) in DMF (5 mL) was stirred at 50° C. for 12 h. Water (20 mL) was added to and extracted with ethyl acetate (2×20 mL). The organic layers were dried over Na2SO4, filtered and concentrated to give (1S,4S)-5-(6-chloro-2-(methylthio)pyrimidin-4-yl)-2-oxa-5-azabicyclo-[2.2.1]heptane (550 mg, 92.5% yield) as a white solid, which was used for next step without further purification LCMS (ESI): [MH]+=258.0.
