Reaction Steps

To a solution of 4-[4-morpholin-4-yl-6-(3-oxa-8-azabicyclo[3.2.1]oct-8-yl)-1,3,5-triazin-2-yl]aniline (22 mg, 0.06 mmol) in CHCl3 (1 mL) were added Et3N (25 mL, 0.18 mmol) and triphosgene (18 mg, 0.06 mmol). The mixture was stirred at room temperature for 15 min and 4-aminopyridine (17 mg, 0.18 mmol) was added. The mixture was stirred at room temperature overnight. The solvent was removed, and the residue was subjected to HPLC separation to give the title compound as off-white solid (1TFA salt, 8.8 mg, 24% yield). MS (ESI) m/z 489.2.
