Conditions

Temperature: 130 °C

Procedure

A microwave vial was charged with 1-(2-(tert-butyldimethylsilyloxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-(methylsulfonyl)pyrimidin-4-yl)pyridin-2(1H)-one (150 mg, 0.280 mmol), 5-amino-2-oxa-bicyclo[2.2.1]heptan-3-one (89 mg, 0.70 mmol), a drop of concentrated HCl, and s-butanol (2.0 mL). The mixture was stirred at 130° C. under microwave irradiation for 3 hours. After completion of the reaction, the mixture was concentrated to give 1-((S)-2-(tert-butyldimethylsilyloxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-(3-oxo-2-oxa-bicyclo[2.2.1]heptan-5-ylamino)pyrimidin-4-yl)pyridin-2(1H)-one (164 mg, 100% yield), which was used in the next step without further purification. LCMS (ESI) m/z: 285.2 [M+H]+.
