実験手順

7.0 mL of N,N-diisopropylethylamine was added to tetrahydrofuran (70 mL) solution of 4.40 g of ethyl 4,6-dichloronicotinate and 3.44 g of tert-butyl 1-allylhydrazinecarboxylate obtained in Production Example 1-1, and stirred overnight at 70° C. 30 mL of toluene was added to the reaction liquid, and tetrahydrofuran was evaporated away. This was stirred at 120° C. for 6 hours, and then heated overnight under reflux. The reaction liquid was restored to room temperature, water was added thereto, and extracted with ethyl acetate. This was washed with saturated saline water, dried with anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified through silica gel column chromatography (hexane/ethyl acetate=16/1 to 12/1) to obtain 1.29 g of the entitled compound as a colorless oily substance.
