Reaction Steps

To a mixture of 1.09 g of methyl 2-(4-methoxycarbonylphenylthio)-5-nitrobenzoate obtained in the same procedures as described in Reaction Scheme (24) of Example 1 and 1.75 g of iron powder, were added 3 ml of isopropyl alcohol and an aqueous solution of ammonium chloride (0.05 g of ammonium chloride and 0.95 ml of water). The mixture was stirred for 10 minutes at 85° C. Chloroform was added to the reaction mixture. The mixture was filtered with celite, and was subsequently washed with chloroform. A mixture of the filtrate and the washing was washed with saturated brine, and was subsequently dried over anhydrous magnesium sulfate. After the solvent was removed under reduced pressure, 0.996 g of methyl 5-amino-2-(4-methoxycarbonylphenylthio)benzoate (yellow viscous substance) was obtained (Reaction Scheme (31) described below).
