In a 50 mL volume pressure-resistant vessel were placed 2.02 g (6.58 mmol) of methyl 5-methoxy-4-(3-chloropropoxy)-2-nitrobenzoate (purity: 99%) obtained in Reference Example III-4, 2.0 g of a developed Raney nickel, and 40 mL of methanol. The atmosphere in the vessel was replaced with hydrogen, and the vessel was closed. The reaction was carried out at 90-100° C. for 24 hours at a hydrogen pressure of 0.9 MPa (gauge pressure). After the reaction was complete, the reaction mixture was filtered. The filtrate was analyzed by high performance liquid chromatography (absolute quantitative analysis). There was produced 1.71 g (reaction yield: 95.0%) of methyl 5-methoxy-4-(3-chloropropoxy)anthranilate.
