Participants

Reaction Steps

A solution of n-propylamine (3.0 mL, 36 mmol) in dichloromethane (75 mL) was cooled to 0° C.; trimethylaluminum (available as a 2 M solution in toluene, 18 mL, 36 mmol) was added dropwise with stirring over a period of three minutes. The reaction was stirred for one hour at 0° C. and 30 minutes at ambient temperature. A solution of ethyl 4-(2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)butanoate (5.80 g, 17.8 mmol, prepared as described in Parts A-D of Example 1) in dichloromethane (30 mL) was added, and the reaction was then heated at reflux for three days. The work-up procedure described in Part E of Example 1 was followed to provide N-propyl-4-(2-propyl-1H-imidazo[4,5-c]quinolin-1-yl)butanamide as a brown oil.
