Reaction Steps

In a 40 mL vial were mixed 5-bromo-2-chloro-4-methylpyrimidine (438 mg, 2.109 mmol), (1R,5S)-3-azabicyclo[3.1.0]hexane-2-carboxylic acid (295 mg, 2.320 mmol), and Et3N (0.882 mL, 6.33 mmol) in EtOH (90 mL). The resulting yellow solution was stirred at 75° C. for 3 days. The reaction mixture was subsequently partitioned between 1N HCl (40 mL) and EtOAc (40 mL). The phases were separated and the aqueous layer was back-extracted with EtOAc (75 mL). The organic layers were combined, washed with brine (40 mL), dried over Na2SO4, filtered, and concentrated to give the title compound as a white solid, which was used without further purification (660 mg).
