Reaction Steps

To a solution of 8-oxa-3-azabicyclo[3.2.1]octane hydrochloride (0.49 g, 3.3 mmol) in water (18 mL) was added a suspension of tert-butyl 4-(4,6-dichloro-1,3,5-triazin-2-yl)piperazine-1-carboxylate (1.0 g, 3.0 mmol) in acetone (about 10 mL). The suspension was stirred magnetically while solid sodium carbonate (0.70 g, 6.6 mmol) was added in a single portion. The mixture was stirred for two hours while heating in a 70-75° C. in an oil bath. After allowing the mixture to cool to room temperature, the title compound was removed by filtration, washed with water, and dried under vacuum.
