実験手順

The general method described in Part A of Example 3 was followed. Triethyl orthopropionate (7.66 mL, 58.1 mmol) was added in lieu of triethyl orthoacetate to a solution of 7-benzyloxy-N4-(2-methylpropyl)quinoline-3,4-diamine (18.68 g, 58.11 mmol) in xylenes (200 mL). At the end of the reaction, the precipitate was collected in three crops to provide 7.16 g of 7-benzyloxy-2-ethyl-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinoline as a light-brown solid, mp 127° C.
