7-benzyloxy-1-(2-methylpropyl)-2-propyl-1H-imidazo[4,5-c]quinolin-4-amine → 2-ethyl-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-7-ol

Participants

Reaction Steps

The general method described in Part J of Example 1 was followed using 7-benzyloxy-2-ethyl-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinoline (3.43 g, 9.54 mmol) in lieu of 7-benzyloxy-1-(2-methylpropyl)-2-propyl-1H-imidazo[4,5-c]quinolin-4-amine. The crude product was recrystallized from acetonitrile, isolated by filtration, and dried for two days in an oven at 60° C. to provide 0.92 g of 2-ethyl-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-7-ol as an off-white solid, mp >250° C.
