Procedure

Triethylamine (33 mL, 240 mmol) was added to a suspension of a mixture containing 4-(chloromethyl) quinoline (Reference Compound No. 5-1, 17.0 g) and 2-mercaptonicotinic acid (13 g, 86 mmol) in anhydrous N,N-dimethylformamide (200 mL) at room temperature, and the mixture was stirred for 48 hours. Water (700 mL) and ethyl acetate (400 mL) were added thereto. After the mixture was separated into the organic layer and the aqueous layer, 1N hydrochloric acid (50 mL) was added to the aqueous layer. The precipitated solid was filtered off and dried under reduced pressure at 60° C. to give 15 g of the title Reference Compound as a yellow solid (Yield: 59%).
