Phthalimide potassium salt → HCID 57515472, compound

Participants

Reaction Steps

Potassium phthalimide (2.59 g, 14.0 mmol) was added to a solution of 1-[(4-amino-2-chloromethyl-1H-imidazo[4,5-c]quinolin-1-yl)methyl]cyclohexanol (13.3 mmol) in DMF (50 mL). The reaction mixture was stirred at ambient temperature overnight. Additional potassium phthalimide (1.0 g) was added. The reaction mixture was stirred for 5 hours and then concentrated under reduced pressure. The residue was triturated with methanol to provide 6.91 g of crude 2-({4-amino-1-[(1-hydroxycyclohexyl)methyl]-1H-imidazo[4,5-c]quinolin-2-yl}methyl)isoindole-1,3-dione as a white solid.
