실험 절차

Iron powder (0.6 g), ammonium chloride (1.4 g), ethanol (100 ml) and water (30 ml) were added to the 7-benzyloxy-6-cyano-4-(4-nitrophenoxy)quinoline obtained in Production Example 5, and the mixture was stirred at 90° C. for 2.5 hours. The reaction system was returned to room temperature and then filtered with celite, the filtrate was subjected to liquid separation, and the organic layer was washed with water and saturated saline in that order, dried over sodium sulfate and then concentrated to dryness under reduced pressure to obtain 1.31 g of a crude product containing the target substance. The crude product was used directly for the following reaction. (Production Example 7).
