Procedure

After adding trifluoroacetic acid (30 ml) and thioanisole (3 ml) to 7-benzyloxy-6-methoxy-4-(4-nitrophenoxy)quinoline (4.0 g), the mixture was heated and stirred at 70° C. for 2 hours. After cooling the reaction solution, it was concentrated under reduced pressure, sodium bicarbonate water and methanol were added and the precipitated crystals were filtered out. They were then washed with diethyl ether to obtain 4.0 g of the title compound.
