Phthalimide → 2-((4-(2-(Cyclohexylmethylamino)benzo[d]oxazol-6-yloxy)pyridin-2-yl)methyl)isoindoline-1,3-dione

Participants

Reaction Steps

To a solution of the (4-(2-(cyclohexylmethylamino)benzo[d]oxazol-6-yloxy)pyridin-2-yl)methanol (20 mg, 0.057 mmol, 1.0 eq) in 2 mL of THF was added triphenyl phosphine (22 mg, 0.085 mmol, 1.5 eq), phthalimide (12.5 mg, 0.085 mmol, 1.5 eq) and diisopropyl azodicarboxylate (17 mg, 0.085 mmol, 1.5 eq) at room temperature. The reaction mixture was stirred at that temperature for 16 hours. Then the solvent was removed. The crude product was purified by preparative TLC sheet to give 2-((4-(2-(cyclohexylmethylamino)benzo[d]oxazol-6-yloxy)pyridin-2-yl)methyl)isoindoline-1,3-dione.
