Participants

Reaction Steps

5,6-Diamino-2-[2-(pyridin-2-yloxy)-ethoxy]4-morphlinopyrimidine (0.332 g, 1.00 mmol, 1.00 equiv.) and m-tolyl isocyanate (0.133 g, 1.00 mmol, 1.00 equiv.) were mixed in 10 mL THF and stirred at room temperature for 15 hours. THF was removed, and the residue was treated with POCl3 in 2 mL CH3NO2 at 100° C. for 30 minutes. The reaction mixture was neutralized with 2N NaOH solution at 0° C., and subjected to EtOAc extraction. The organic solution was dried over MgSO4, filtered through a plug of silica gel, concentrated to around 2 mL, and cooled to 0° C., resulting in formation of the titled compound as off-white crystal which was collected by filtration, washed with EtOAc, and dried (0.095 g, 0.212 mmol, 21.2% yield).
