Participants

Reaction Steps

Triethylamine (4.6 mL, 33.1 mmol) was added to a solution of N-hydroxyphthalimide (2.16 g, 13.2 mmol) in DMF (10 mL). A solution of tert-butyl[3-(4-amino-2-chloromethyl-1H-imidazo[4,5-c]quinolin-1-yl)propyl]carbamate (4.3 g, 11.0 mmol) in DMF (20 ml) was added. The reaction was stirred at ambient temperature for 3.5 hours and then diluted with water (100 mL). The resulting precipitate was isolated by filtration, washed with water, and then dried in a vacuum oven at 60° C. over the weekend to provide 4.25 g of tert-butyl (3-{4-amino-2-[(1,3-dioxo-1,3-dihydroisoindol-2-yl)oxymethyl]-1H-imidazo[4,5-c]quinolin-1-yl}propyl)carbamate as a light yellow solid.
