実験手順

1-{[3-Amino-7-(benzyloxy)quinolin-4-yl]amino}-2-methylpropan-2-ol, prepared as described in Parts A and B of Example 54, was treated according to the general methods described in Parts C and D of Example 54 with ethoxyacetyl chloride used in lieu of acetoxyacetyl chloride in Part C. The product, (7-benzyloxy-2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-1-yl)-2-methylpropan-2-ol, was treated according to the general methods of Parts F and G of Example 54 to provide (4-amino-7-benzyloxy-2-ethoxymethyl-1H-imidazo[4,5-c]quinolin-1-yl)-2-methylpropan-2-ol as a white powder, mp 215.1-215.5° C.
